If displacement of a particle is zero, distance covered by it

Question

If displacement of a particle is zero, distance covered by it (A) may be zero or may not be zero (B) must be zero (C) must not be zero (D) all are true

When displacement is zero, particle may be at rest, therefore, distance travelled = 0.
Again, when displacement is zero, final position coincides with the initial position, distance travelled is not zero.

may be zero or may not be zero

must be zero

must not be zero

all are true
