Answer

: C. We visited gardens, fountains, and monuments during our trip.

Brief Explanations:

In English grammar, when listing items (gardens, fountains, monuments), a comma is used before "and" (Oxford comma). Also, there should be no comma after "visited" (as it's not an introductory phrase) and no comma before "during" (as it's not a non - essential clause). Option C follows these comma rules correctly.
