the answers are b c d

 

a is incorrect because an accelerated particle may have zero velocity at some point of time like a stone thrown up have zero velocity at highest point despite being constantly accelerated.

b is correct because it s possible that a particle dont experience any force and stay at rest.

c is correct because without any acceleration speed of any particle canot change.

d is correct because there is no change in speed or velocity so there was no acc.
