A body \( A \) rests on \( B \) and friction coefficient between \( A \) and \( B \) is \( \mu \). Block \( M \) is placed on a frictionless surface. Then
(i)
(ii)
(a) The maximum possible value of \( F \) so that both bodies move together in case (i) is \( \mu(M+m) g \).
(b) The maximum possible value of \( F \) so that both bodies move together in case is \( \mu \mathrm{mg} \).
(c) The maximum possible value of \( F \) so that both bodies move together in case (ii) is \( \mu(M+m) g \).
(d) The maximum possible value of \( F \) so that both bodies move together in case (ii) is \( \mu \mathrm{mg} \).
