Answer 2

Option (C) is correct.

Logical address space can be smaller than physical address space.

About memory :

• The assertion is correct. Because a portion of the program must be stored in memory during execution, the logical address space might be significantly bigger than the physical address space.

• The main distinction between logical and physical addresses is that a logical address is created by the CPU in the context of a program, whereas a physical address is a memory location.
