External fragmentation is increased with small pages is correct statement.

Internal Fragmentation is increased with small pages. This is a correct statement.

Can anyone tell me the correct answer? Please.

I agree @Umaima.

External fragmentation.

Total memory space is enough to satisfy a request or to reside a process in it, but it is not contiguous so it can not be used.

Internal fragmentation.

Memory block assigned to process is bigger. Some portion of memory is left unused as it can not be used by another process.

Please tell me the concept in detail.

External fragmentation is increased with small pages is correct statement.

Rarely do processes require the use of an exact number of pages. As a result, the last page will likely only be partially full, wasting some amount of memory. Larger page sizes increase the potential for wasted memory this way, as more potentially unused portions of memory are loaded into main memory. Smaller page sizes ensure a closer match to the actual amount of memory required in an allocation.

As an example, assume the page size is 1024KB. If a process allocates 1025KB, two pages must be used, resulting in 1023KB of unused space (where one page fully consumes 1024KB and the other only 1KB).

So, I think the answer should be A.
