Right choice is (d) all of the mentioned

To explain I would say: The 80286 in real addressing mode performs the following functions: it initializes IP and other registers of 80286, initializes the peripheral, enables interrupts, sets up descriptor tables, and then prepares it for entering the protected virtual address mode.
