crabs instead of carbs

I. Some bats are crabs → False (it is possible but not definite).

II. No crab is ant → False (some ants are crabs)

III. No bat is crab → False (it is possible but not definite).

Here, I and III form a complementary pair.

Hence, “either conclusion I or III follows” is the correct answer.
