Reason (R) : Enthalpy of hydration for Cu2+\mathrm{Cu^{2+}}Cu2+ is much less than that of Cu+\mathrm{Cu^{+}}Cu+. In the light of the above statements, choose the correct answer from the options given below :
  1. A
    (A) is correct but (R) is not correct
  2. B
    Both (A) and (R) are correct but (R) is not the correct explanation of (A)
