In a block mapping system, suppose that a is a base address stored in the block map table origin register and that the block map table for the process with base address a contains the real address b' for the start of virtual block b in main memory and the real address d' for the start of virtual block d in main memory. What is the real address of virtual address v = (b, d)?
A) b' + d
B) d' + b
C) a + b'
D) a + d'

The real address of a virtual address v = (b, d) in a block mapping system is calculated by adding the real address of the start of the virtual block b (which is b') to the offset d within that block.
