For small works the small size of aggregate will be used.

For RCC-20mm.
For massive structures -40 mm is permissible.
Here in this question 10 mm is correct.

Whst is the reason behind it? Please explain.

It is 20mm.

It depends upon the thickness of floor and purpose for which floor is to be designed.

Generally, in case of massive construction such as dam we use 40mm aggregate size.

For floor and in case of reinforced member we use the 20mm size of aggregate similarly for normal floor aggregate size should be 10mm.

20mm is not enough for reinforcement 18mm is enough for it.

40MM agg get up to 200kg/cm2 strength.
20MM agg get up to 300kg/cm2 strength in construction.
