If A -> B and B -> C, what follows from A?

Transitivity of implication is being tested. If A implies B and B implies C, then A implies C. See it by chaining: assume A is true, then A -> B gives B is true, and B -> C then yields C is true. So A -> C follows from the two premises. The other options don’t follow from A using this chain—A -> B and B -> C are the given premises, not the result of deriving from A alone, and Not A is not forced by the information given.
