? None of the these

The address generated by the CPU while a program is running is called Logical Address.

Explanation:

The part of the operating system that manages the memory is called memory manager and its job is to keep a record of the parts of memory that are being used and those that are not, in order to allocate memory space to processes when they are need and releasing it when they finish. The concept of logical address space linked to a separate physical address space is crucial for good memory management. Logical address is the address that generates the process and physical address is the address perceived by the memory unit. Logical and physical addresses differ in the linking scheme at runtime. The correspondence between virtual and physical addresses at runtime is established by a hardware device called the management unit of memory. The relocation record adds to all addresses generated by a process of user at the time of sending them to memory, in order to generate the physical addresses corresponding.
