What will be the output of this code snippet?

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
print(GPIO.gpio_function(7))

Assuming pin 7 is set as input by default.

A1 (GPIO.OUT)

B2 (GPIO.SPI)

C0 (GPIO.IN)

DRaises an error

Step-by-Step Solution

Solution:

Step 1: Understand GPIO.gpio_function
This function returns the current mode of the pin (input, output, etc.).
Step 2: Default pin mode for BOARD pin 7
Pin 7 defaults to input mode, which is represented by 0 (GPIO.IN).
Final Answer:
0 (GPIO.IN) -> Option C
Quick Check:
Default pin mode = GPIO.IN (0) [OK]

Quick Trick: Default pin mode is input (0) unless set otherwise [OK]
