Answer 2

Answer:

(A) FALSE

Explanation:

(A) A body has a constant velocity but a varying speed. (FALSE)

(B) A body has a constant speed but a varying value of acceleration.( FALSE)

(C) A body has a constant speed and non-zero constant acceleration.( TRUE)

(D) A body has a constant speed but a varying velocity.(FALSE)

Acceleration does not depend on speed, acceleration depends on velocity which is speed + direction. Due to the direction change , speed remains constant.
