Agree @Shub.
Add that rounded aggregate has less surface area than give better workability in same condition.

The rounded shape aggregate is the correct answer.

Angular aggregate is the correct answer.

The higher surface area of angular aggregate with rough texture requires more water for a given workability than the rounded aggregate. This means that for a given set of conditions from the point of view of water-cement ratio and consequent strength, rounded aggregate gives higher strength.

Angular aggregate is best option than rounded aggregate. But the rounded aggregate is also used so, I agree.

@Ajeet & @Bakum.
Thanks for clarification between both rounded and angular one.

Rounded is the correct answer. I agree.

Since the rounded aggregates need least water cement ratio hence it is preferred for in case of workability. But angular has interlocking pattern that rounded lack and hence in case of bonding angular is better.

In case of work ability, rounded are better than angular while in case of bonding, Angular is best but overall angular aggregates are good. So for this particular question. Rounded is correct answer.
