Find the bug in this code:

import csv
with open('input.csv', 'r') as f:
    reader = csv.DictReader(f)
    for row in reader:
        print(row['Name'])

Assuming the CSV header is name,age (all lowercase).

ANo bug, code runs fine

BFile should be opened in binary mode

CMissing delimiter parameter in DictReader

DKeyError due to case mismatch in dictionary key

Step-by-Step Solution

Solution:

Step 1: Check CSV header and key used in code
CSV header is 'name' lowercase, but code accesses 'Name' with uppercase N.
Step 2: Understand dictionary key sensitivity
Dictionary keys are case-sensitive, so 'Name' key does not exist, causing KeyError.
Final Answer:
KeyError due to case mismatch in dictionary key -> Option D
Quick Check:
DictReader keys are case-sensitive [OK]

Quick Trick: Match dictionary keys exactly to CSV headers (case-sensitive) [OK]
