When air resistance is ignored, a stone is projected from $P$ and moves along a parabolic trajectory, with $T$ as the highest point it attains. The stone passes through $Q$ immediately before it lands. The vertical component of acceleration of the stone is
- Azero at $T$.
- Blarger at $T$ than at $Q$.
- Clarger at $Q$ than at $T$.
- Dthe same at $Q$ as at $T$.
