At launch, you have full velocity, full acceleration, but after launch you have air fiction lowering acceleration.

At the start of projectile where are must be less and are is inversely proportional to acceleration so at the start of the projectile the acceleration is maximum.

Projectile: Pv and Ph forces act simultaneously.
Any vehicle wheel has max acceleration at it starts only...
Therefore, it has max acceleration at the start only.

At the start. Why? Explain.

At the start, velocity becomes zero so acceleration also zero. Then why is the answer option A? Please explain.

Centripetal acceleration = v^2/r.
Velocity is Zero at the top and increases towards the ground, reaches maximum before strikes it.
For max acceleration --> max velocity --> as it strikes the ground.
