A block B is placed on block A.The mass of block B is less than the mass of block A. Friction exists between the blocks, whereas the ground on which the block A is placed is taken to be smooth.A horizontal force F increasing linearly with time begins to act on B.The acceleration aA​ and aB​ of block A and B respectively are plotted against L .The correctly plotted graph is
