Answer 1

any ideas? as a hint try removing all the words except for the subject + verb (be careful with this)

A) cheeses are
B) cheeses sells
C) Swiss cheese or Gruyere cheese make
D) cheese were

cheeses is plural so it would normally take a singular noun (ex. cheeses smell not cheeses smells)
cheese is singular so it would normally take a plural noun (ex. cheese smells not cheese smell)

an important exception is when you have the word "or"

in the third example, you have Swiss cheese or Gruyere cheese make

when considering singular object vs plural verb in this case, consider the noun closest to the verb

"Gruyere cheese make"

which is not grammatically correct according to our previous rules

Answer 2

that being said, between A B or D which one do you think is the best choice?
