Tripling the concentration of A will triple the reaction rate.

Explanation:

For a first-order reaction hat has a rate law:

Rate = k[A].

It is clear that the reaction rate is directly proportional to the concentration of A.

Rate ∝ [A].

So, Tripling the concentration of A will triple the reaction rate.
