Two blocks A and B of masses m$$_A$$ = 1 kg and m$$_B$$ = 3 kg are kept on the table as shown in figure. The coefficients of friction between A and B is 0.2 and between B and the surface of the table is also 0.2. The maximum force F that can be applied on B horizontally, so that the block A does not slide over the block B is:
[Take g = 10 m/s$$^2$$]

A

16 N

B

12 N

C

40 N

D

8 N
