A block A of mass

4 \text{ kg}

is placed on another block B of mass

5 \text{ kg}

, and the block B rests on a smooth horizontal table. If the minimum force that can be applied on A so that both the blocks move together is

12 \text{ N}

, the maximum force that can be applied to B for the blocks to move together will be: (1)

30 \text{ N}

(2)

25 \text{ N}

(3)

27 \text{ N}

(4)

48 \text{ N}
