As per IS 383:2016 ...grading of aggregates.
Course agg:- 80mm 63mm 40mm 20mm 16mm 12.5mm 10mm 4.75mm 2.36mm.
Fine agg:- 10mm 4.75mm 2.36mm 1.18mm 600 micron 300 micron 150 micron.
For Fineness modulus:
Course aag:- 80mm 40mm 20mm 10mm 4.75mm 2.36mm 1.18mm 600mic 300mic 150mic.
Fine agg:- 4.75mm 2.36mm 1.18mm 600mic 300mic 150mic.
Course agg:- 80mm 63mm 40mm 20mm 16mm 12.5mm 10mm 4.75mm 2.36mm.
Fine agg:- 10mm 4.75mm 2.36mm 1.18mm 600 micron 300 micron 150 micron.

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.

Actually, the question is wrong as coarse aggregates contain 20mm and 40mm aggregates also not only 10mm. And max sieve size to determine the size of fine aggregates is 4, 75.

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.
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.

80, 40, 20, 10, 4.75 ----->> Coarse aggregates.
4.75, 2.36, 1.18, 600 micron, 300 micron, 150 micron ---->> Fine Aggregates.
4.75, 2.36, 1.18, 600 micron, 300 micron, 150 micron ---->> Fine Aggregates.

Here, fine aggregates can also sieve along with course aggregates.
It is possible then sived with< 4.75 size sives.
It is possible then sived with< 4.75 size sives.

The aggregate of size more than 75 mm are called Cyclopean aggregate. Since the Max size of coarse aggregate is 75 mm.

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