At t=0, the particle was at its equilibrium position. The time period is 32 seconds, so in 8 seconds, it will reach the extreme location once, and hence, in 8 seconds, it will cover a distance equivalent to its amplitude.

Acceleration is defined as rate of change in velocity
So we can write its formula as
here we know that
= final velocity = 56 m/s
= initial velocity = 7.6 m/s
t = time interval to change the velocity = 3 s
now we will plug in all values in the above equation
so here roller coaster will accelerate at rate of 16 m/s^2 and hence correct answer is "option d"
