Question

I... This word a) am not understanding b) wasn't understanding c) dont understand c) doesn't understand

Answer 1

I c) don't understand this word.

Answer 2

The correct answer is:

c) don't understand

The word "don't" is a contraction of "do not," which is used when referring to yourself or a plural subject. In this case, since "I" is the subject, you would use "don't understand" to indicate that you currently do not understand something.
