Mark the true statement. A particle in one-dimensional motion

Question

Mark the true statement. A particle in one-dimensional motion (A) with zero speed at an instant may have non-zero acceleration at that instant (B) with non-zero speed may have non-zero velocity (C) with constant speed, may not have zero acceleration (D) with positive value of acceleration must be speeding up

A ball thrown vertically up has zero speed at the highest point, but an acceleration vertically downwards.

Q. Mark the true statement. A particle in one-dimensional motion

with zero speed at an instant may have non-zero acceleration at that instant

with non-zero speed may have non-zero velocity

with constant speed, may not have zero acceleration

with positive value of acceleration must be speeding up

A ball thrown vertically up has zero speed at the highest point, but an acceleration vertically downwards.
