Answer

Explanation:

Step1: Understand dictionary indexing

In Python, when you have a dictionary like grades = {100:'A', 75:'C', 89:'B', 80:'B'}, and you use grades[75], you are accessing the value associated with the key 75.

Step2: Identify the value

The key 75 is associated with the value 'C' in the grades dictionary.

Answer:

D. 'C'
