Q: Answer-'External fragmentation' in a memory management scheme refers to a situation where:

External fragmentation occurs when the total amount of free memory in the system would be enough to satisfy a request, but that free memory is broken up into multiple small, non-contiguous blocks scattered between allocated regions, so no single free block is large enough to satisfy the request as a whole.

A A single allocated partition contains unused space larger than what the process actually needs

B The CPU cache is unable to hold an entire page table

C A file is stored in non-contiguous disk blocks

D A process is denied memory because the system has run out of total physical memory entirely

E The total free memory is sufficient to satisfy a request, but it exists as multiple small, non-contiguous blocks scattered between allocated partitions, none of which is individually large enough
