Explanation:

Question 16

To identify logic errors, hand - tracing (going through the code step - by - step manually) is effective as it helps in understanding the flow and logic. Creating new test cases, rerunning with different inputs, or running a simulation are less focused on the internal logic flow compared to hand - tracing.

When a program tries to access an invalid index in a list during its execution, it's a runtime error. Logic errors are about wrong logic, overflow is about exceeding data size limits, and syntax errors are about code structure violations. Accessing an invalid index happens while the program is running.

Event - driven programming responds to events. A mobile device orienting to a new position is an event (change in orientation) that the device's program responds to. Prompting for user response is more of user - interaction, using constants is about data handling, and a microphone transmitting audio is data input, not event - driven in the sense of responding to an event like orientation change.

Answer:

B. Hand - tracing
