Answer: D

Explanation: A doesn't make sense, B doesn't either.

However you're left with C and D. In this case I can understand if you picked C, but I picked that and got the answer wrong.

D makes sense since data abstraction means to simplify the code to make it easy to read and point out details while removing other components.

A function allows one to understand the intention of the code by its name and thus it makes it easier to read.

Therefore, I suggest D.

It would be most helpful in this option because it has been reduced to individual variables instead of the full list of the students
