A block `B` is placed on the 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 block `A` is placed is taken to be smooth. A horizontal force `F`, increasing linearly with time begins to act on `B`. The acceleration `a_(A)` and `a_(B)` of blocks `A` and `B`, respectively , are plotted against `t`. The correctly plotted graph is
