0.6Kg of A/1.6kg of solution = 0.375 At 60° C.
0.2 kg of A/1.2 kg of solution = 0.166 At 25° C.
Crystal formed = 0.375 - 0.1666 = 0.2084.
0.2 kg of A/1.2 kg of solution = 0.166 At 25° C.
Crystal formed = 0.375 - 0.1666 = 0.2084.

I think B should be the right answer.
OMB: F = L +C.
A bal: F*(0.6/1.6) = L (0.2/1.2) + C.
C = 0.25.
OMB: F = L +C.
A bal: F*(0.6/1.6) = L (0.2/1.2) + C.
C = 0.25.
