xPortGetFreeHeapSize()returns current free heap memory.Step 2: Identify stack monitoring function
uxTaskGetStackHighWaterMark()returns minimum stack space left for a task.Step 3: Exclude unrelated functions
vTaskDelay(),vTaskDelete(), andvTaskSuspend()are task control functions, not memory monitoring.Final Answer:

Heap + stack monitoring = xPortGetFreeHeapSize() + uxTaskGetStackHighWaterMark() [OK]
