○ 515

Explanation:

Step1: Analyze the function `sum_to`

The function `sum_to(num)` initializes `sum` as 0, then loops over `i` in `range(num + 1)`, adding each `i` to `sum`. So it calculates the sum of integers from 0 to `num`.

Step2: Calculate for `num = 5`

For `num = 5`, the loop runs for `i = 0, 1, 2, 3, 4, 5`. The sum is \(0 + 1 + 2 + 3 + 4 + 5=\frac{5\times(5 + 1)}{2}=15\) (using the formula for the sum of the first \(n\) positive integers, \(S=\frac{n(n + 1)}{2}\), here \(n = 5\)). Then `sum_to(5)` returns 15, and `print(x)` with `x = 5` prints 5? Wait, no, looking at the code: `x = 5`, `sum_to(x)` (which calculates sum 0 - 5 = 15, but then `print(x)` prints 5? Wait, no, the code is:
```python
def sum_to(num):
sum = 0
for i in range(num + 1):
sum += i
print(sum)

x = 5
sum_to(x)
print(x)
```
Wait, no, the user's code: `x = 5`, `sum_to(x)` (which in the function `sum_to` prints `sum`), then `print(x)`. Wait, the function `sum_to` has `print(sum)`, so when `sum_to(5)` is called, it calculates sum from 0 to 5: \(0+1+2+3+4+5 = 15\), so it prints 15. Then `print(x)` where `x = 5` prints 5? But the options include 15? Wait, maybe the code was misread. Wait, the user's code:
Looking at the image:
```
def sum_to(num):
sum = 0
for i in range(num+1):
sum += i
print(sum)

x = 5
sum_to(x)
print(x)
```
Wait, no, the last lines: `x = 5`, `sum_to(x)`, `print(x)`? Wait, no, the code as per the image: `x = 5`, `sum_to(x)`, `print(x)`? Wait, no, the `sum_to(x)` calls the function which prints `sum` (the sum from 0 to 5, which is 15), then `print(x)` prints 5? But the options: one of them is 15? Wait, the options given are "5 15" (maybe two prints: first from `sum_to(5)` which is 15, then `print(x)` which is 5. But maybe the question is about the output of the program. Let's re - evaluate:

Function `sum_to(5)`:
- `sum` starts at 0.
- Loop `i` from 0 to 5 (inclusive, since `range(5 + 1)` is 0 - 5).
- Sum: \(0+1+2+3+4+5 = 15\), so `print(sum)` in the function prints 15.
Then `print(x)` with `x = 5` prints 5. But maybe the question is about the output of `sum_to(5)`? Wait, the options: "5 15" or maybe a typo. Wait, the options shown are "5 15" (maybe two outputs: 15 from `sum_to(5)` and 5 from `print(x)`). But if the question is about the output of the program, the first print from `sum_to(5)` is 15, and the second `print(x)` is 5. But maybe the user's question is about the output of `sum_to(5)`, which is 15, and then `print(x)` is 5. But looking at the options, one of them is 15 (maybe the first output). Wait, let's recalculate the sum:

Sum from 0 to \(n\) is \(\sum_{i = 0}^{n}i=\frac{n(n + 1)}{2}\). For \(n = 5\), \(\frac{5\times6}{2}=15\). So the function `sum_to(5)` prints 15, and then `print(x)` (where \(x = 5\)) prints 5. But maybe the question is about the output of the program, so the outputs are 15 and 5. But the options given: "5 15" (maybe the order is 15 then 5? No, the code is `sum_to(x)` (prints 15) then `print(x)` (prints 5). So the outputs are 15 and 5. But if the question is about the output of `sum_to(5)`, the answer is 15. If it's about the two prints, 15 and 5.

Wait, the user's code:
```
def sum_to(num):
sum = 0
for i in range(num + 1):
sum += i
print(sum)

x = 5
sum_to(x)
print(x)
```
When we run this code, first `sum_to(5)` is called. Inside `sum_to`, the loop runs for `i` from 0 to 5, sum becomes 15, and `print(sum)` prints 15. Then `print(x)` (where `x = 5`) prints 5. So the output is 15 followed by 5. But maybe the question is about the output of the `sum_to` function call, which is 15.

Answer:

15 (and 5 if considering both prints, but the main sum from 0 - 5 is 15)
