In a paged segmented scheme of memory management, the segment table itself must have a page table because

  1. The segment table is often too large to fit in one page
  2. Each segment is spread over a number of pages

  3. Segment tables point to page tables and not to the physical locations of the segment

  4. The processor’s description base register points to a page table

Option (B) is true for segmented paging(segment size becomes large so paging done on each segment) which is different from paged segmentation(segment table size becomes large and paging done on segment table)

Here option (A) is true , as segment table are sometimes too large to keep in one pages. So, segment table divided into pages. Thus page table for each Segment Table pages are created.

For reference , read below :

C)Yes that is correct , segment table not point to actual location of page table, because segment table is the users view on page table, but it is not the reason for each segment table must have a page table

D)Base register points to the page table, i.e. not cause for each segment has separate page table
