Best answer
Correct option is (c) page interleaving

Easy explanation: The accessing of data outside the page boundary can cause missing of pages in the page mode operation. So a program has to operate for frequently accessing data thereby, increasing the efficiency in the page selection. One such mode is the page interleaving mode in which the memory is divided into different banks, depending on the number of memories installed.
