Answer B is correct.(q2/g)^1/3 = 0.46, which is greater than 0.25.

yc = (q2/g)1/3 = 0.46.
Option B is correct because 0.25less than 0.46, critical depth is more means steep slope.

How 0.46 could came?

Yeah, you guys are right, I agree with the option B.

Yes @Dhawal, you guys are right it is Steep yc = 0.46 and yn = 1.

How the calculation made 0.46?
DHAWAL said:

Answer should be steep, as by calculations, critical depth = 0.46 m; whereas given normal depth is 0.25 m, as critical depth>normal depth so it would be steep.

It should be steep slope because critical gradient is more than given depth hence its B only.
