A virtual address is an address that is generated by the CPU. The total address space of CPU-generated addresses is known as virtual address space. A programmer can have only the view of virtual memory whereas physical memory is the actual physical address in a disk. A page table is used to keep track of virtual memory to physical memory mapping, which is done by Memory Management Unit hardware. So, it is obvious that the virtual memory concept comes before pegging. So, the answer is option A.
