A-1, B-2, C-3, D-4 Explanation: A. Hierarchical Paging 1 Explanation: Hierarchical paging splits the page table into multiple levels (such as two-level or multi-level paging) so that the page table itself can be paged, avoiding the need to keep all parts contiguous and resident in memory. B. Hashed Page Tables 2 Explanation: Hashed page tables map virtual page numbers to a hash bucket list, making them highly efficient and common for address spaces larger than 32 bits. C. Inverted Page Table 3 Explanation: An inverted page table maintains only one entry per real physical frame of memory rather than one per virtual page, drastically reducing memory overhead for large address spaces. D. Clustered Page Table 4 Explanation: Clustered page tables are similar to hashed page tables, but each entry in the table maps to multiple
