Recently implemented "virtual lectures" conducted remotely at the request of college students have reduced test scores, grades, discussion among students, and have increased student retention of the material.

A. ..
B. discussion among students, and increased
C. and discussion among students while increasing
D. lowered discussion among students, but increased
E. and discussion among students was reduced while increasing

I think this question deals with listing of items of different types and how to group them.
OA = C

This question is testing the listing of items and also the shift in the writer's opinion.
C correctly shows the parallel action with the use of the word "While".

Another vote for C.

A and B can be ruled out because it doesn't take care of shift of scopre/opinion

D uses both reduced and lowered - wrong usage

E is too wordy.

C takes care of parralel construction as well.
