for LIFO we need to check max time of Loading and for LRU min time of reference.

Yes but given is A i dont know how!

how is page 1 loaded at 280 and last referenced at 256 ?

Answer 1

In LIFO, the page which has been loaded at last will be selected for the replacement

Here, its page 1 since it has the maximum loading time

In LRU, the page the has been referenced longest time in the past will be selected for the replacement.

Here, its page 1 since it has minimum time of reference that means it has referenced before all the pages.

So option D
