Given the following FreeRTOS configuration:

#define configCHECK_FOR_STACK_OVERFLOW 1

What will happen if a task's stack pointer exceeds its allocated stack size?

AvApplicationStackOverflowHook() is called during context switch

BThe system resets immediately without notification

CThe task is suspended silently

DNo detection occurs; overflow is ignored

Step-by-Step Solution

Solution:

Step 1: Understand Method 1 behavior
With configCHECK_FOR_STACK_OVERFLOW set to 1, FreeRTOS checks stack pointer during context switch and calls the overflow hook if overflow detected.
Step 2: Match behavior with options
vApplicationStackOverflowHook() is called during context switch correctly describes the hook call; others describe incorrect or missing behavior.
Final Answer:
vApplicationStackOverflowHook() is called during context switch -> Option A
Quick Check:
Method 1 triggers hook on overflow [OK]

Quick Trick: Method 1 calls hook on overflow during context switch [OK]
