FreeRTOS - RTOS Fundamentals

AblinkLED() is called before readSensor()

BreadSensor() blocks indefinitely, preventing blinkLED()

CThe loop function is missing a return statement

DLED hardware is not connected

Step-by-Step Solution

Solution:

Step 1: Analyze function order and blocking
If readSensor() blocks or takes too long, blinkLED() never executes.
Step 2: Check other options
Calling order is correct; return statement not needed in void; hardware issue not given.
Final Answer:
readSensor() blocks indefinitely, preventing blinkLED() -> Option B
Quick Check:
Blocking function causes no LED blink = A [OK]

Quick Trick: Blocking functions stop later code from running [OK]

Common Mistakes:

Ignoring blocking behavior
Thinking function order causes issue
Assuming hardware problem without evidence
