Answer:

The correct option is 4th option.

Explanation:

The second-chance algorithm is the same as the FIFO algorithm if all pages in memory have been referenced at least once since the last page fault.

In the second-chance algorithm, the page is assigned a reference bit whenever it's visited. therefore the page recently visited isn't swapped out

It works like FIFO. But rather than directly removing the page this algorithm checks for the reference bit. If the reference bit is about the page isn't removed otherwise it's swapped out.
