Solution

The correct option is C
200 MeV

Binding energy of X = 8.5 $\times$ 117 = 994.5 MeV and of Y = 8.5 $\times$ 117 = 994.5 MeV. Total binding energy of X + Y = 1989 MeV. Now, binding energy of U - 236 = 7.6 $\times$ 236 = 1793.6 MeV. Energy liberay=ted = 1989 - 1793.6 = 195.4 MeV.
Hence the closest choice is (c)
