Answer:
Option A

Explanation:
From fundamental equation of motion
where v is the final velocity, u is the initial velocity, a is the acceleration of the body and s is the displacement.
Since the initial velocity is zero
Making acceleration, a the subject of the formula then

Substituting 5 m/s for v and 2.5 m for s then
