What is the error in the following Raspberry Pi Python code for reading a QR code?

from pyzbar.pyzbar import decode
import cv2

image = cv2.imread('qrcode.png')
result = decode('qrcode.png')
print(result)

Aprint() cannot print decode results

Bcv2.imread() is missing

Cdecode() should receive an image, not a file path string

DMissing import for numpy

Step-by-Step Solution

Solution:

Step 1: Check decode() argument type
The decode function expects an image object, not a file path string.
Step 2: Identify the mistake in code
The code passes the string 'qrcode.png' directly to decode, which causes an error.
Final Answer:
decode() should receive an image, not a file path string -> Option C
Quick Check:
decode() needs image object, not filename [OK]

Quick Trick: Pass image object to decode(), not filename string [OK]
