A.

B.

C.
change is to are
D.
The sentence is correctly written.

Answer 1

The correct answer is C. change "is" to "are."

The subject "a large rodent or termites" is a compound subject where "termites" is plural, so the verb should agree with the plural noun, making it "are" instead of "is." The correct sentence would be: "Either a large rodent or termites are responsible for the damage to the garden shed."
