What will be the output if GPIO.cleanup() is not called and the program ends?

AGPIO pins remain set, possibly causing hardware issues

BProgram crashes immediately

CGPIO pins reset automatically by Python

DRaspberry Pi shuts down

Step-by-Step Solution

Solution:

Step 1: Understand GPIO pin behavior after program exit
Without cleanup, pins stay in their last state, which can cause problems.
Step 2: Clarify what happens without cleanup
Python or OS does not reset pins automatically; hardware may be affected.
Final Answer:
GPIO pins remain set, possibly causing hardware issues -> Option A
Quick Check:
No cleanup = pins stay set [OK]

Quick Trick: No cleanup leaves pins active, risking hardware damage [OK]
