This and these are demonstrative pronouns and used as adjective to a noun . This and these can't be used in place of noun. Only option C correctly solves the ambiguity of 'this 'pronoun with proper usage

A. smaller class size, dedicated teachers, and a safe environment are correlated with better academic performance, although this does not imply
B. smaller class sizes, dedicated teachers and safe environments are correlated with better academic performance, although this does not imply
C. smaller class size, dedicated teachers, and a safe environment are correlated with better academic performance, although this correlation does not imply
D. small classes, teachers who are dedicated, and safe environments are correlated with better academic performance, although these do not imply
E. small class sizes, more dedicated teachers, and safe environments are correlated with better academic performance, although it does not imply

Smaller class size represents the number of students and smaller classes means the size of the class room. Also teachers who are dedicated is wordy, dedicated teachers may be used for the same purpose. So eliminate D.

Class size is singular and should not be used as class sizes. Similarly safe environment is correct. Eliminate B and E.

Now we have two options A and C which seem to be correct. Only difference is the word correlation.
This correlation is a better word here to indicate that we are talking about a hypothetical correlation. Only "this" doesn't signify what we are actually talking about.

So, Answer C
