Raspberry Pi - GPIO Basics with Python

What will be the output of this Python code snippet on a Raspberry Pi?

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)
GPIO.output(17, true)
print(GPIO.input(17))

Atrue

Bfalse

CError

Dnull

Step-by-Step Solution

Solution:

Step 1: Check for syntax/runtime errors
GPIO.output(17, true) fails because 'true' is undefined in Python (use True).
Step 2: Confirm program behavior
NameError occurs before print executes, so output is Error.
Final Answer:
Error -> Option C
Quick Check:
'true' not defined -> NameError [OK]

Quick Trick: Python booleans: True/False (capitalized); 'true' -> NameError [OK]
