Explanation:

Step1: Recall the formula for converting Kelvin to Celsius

The formula to convert temperature from Kelvin (K) to Celsius (°C) is $^{\circ}\text{C} = \text{K} - 273.15$.

Step2: Substitute the given value of Kelvin into the formula

We are given the temperature in Kelvin as 288 K. Substituting this into the formula: $^{\circ}\text{C} = 288 - 273.15$.

Step3: Calculate the result

Performing the subtraction: $288 - 273.15 = 14.85^{\circ}\text{C}$, which is approximately $15^{\circ}\text{C}$.

Answer:

B. $15^{\circ}\text{C}$
