Answer is correct.

Because 4.75 is sieve acts as a mediator,

In 4.75 sieve, all coarse aggregates gets retained, while all fines get collected in the pan.

@ALL.

As give IS sieve no 10 and 4.75 mm it means #10 is 2 mm size which is used for fine aggregate and 4.75 used both fine and coarse aggregate.

Greater than 4.75 mm - coarse and else fine.
Datum is 4.75. So both.

Coarse aggregates is the right answer.

Cyclone aggregates more than 75mm.

0.075 - 4.75 mm Fine aggregate.
4.75 - 75 mm Coarse aggregate.
> 75 mm cyclone aggregate.

The answer is correct because aggregate which is retained on 4.75mm sieve are called coarse aggregate and aggregate which passes through the 4.75mm sieve is called fine aggregate so the answer is correct.
