By using the overlays we can execute much greater processes simultaneously which cannot be execute and reside in the memory at the same time. In this the process to be executed process brought to memory only when it is needed at the time of execution.

Explanation:
Overlays are a technique used in memory management to enable a process to be larger than the amount of physical memory available. This is achieved by dividing the program into smaller sections called overlays. Each overlay is loaded into memory as needed and then swapped out when it is no longer needed. This allows the process to be larger than the available physical memory.
The correct option is C, which states that when overlays are used, the size of a process is not limited to the size of physical memory. This is because overlays enable the program to be divided into smaller sections, which can be loaded and unloaded as needed. This allows the process to be larger than the available physical memory.
The other options are not correct because:
- Option A states that overlays are used to increase the size of physical memory, which is not true. Overlays are used to enable a process to be larger than the available physical memory.
- Option B states that overlays are used to increase the logical address space, which is not true. Overlays do not increase the logical address space but enable a process to be larger than the available physical memory.
- Option D states that overlays are used whenever the physical address space is smaller than the logical address space, which is not true. Overlays are used to enable a process to be larger than the available physical memory, regardless of the size of the logical address space.
In summary, overlays are a technique used in memory management to enable a process to be larger than the available physical memory. This is achieved by dividing the program into smaller sections called overlays, which can be loaded and unloaded as needed. When overlays are used, the size of a process is not limited to the size of physical memory.
