Assume that a memory with only 4 pages,each of 16 bytes,is initially empty.The CPU generates the following sequence of virtual addresses and uses the LRU page replacement policy.

0,4,8,20,24,36,44,12,68,72,80,84,28,32,88,92

How many page faults does this sequence cause?What are the page number of the pages present in the main memory at the end of sequence?

A)6 and 1,2,3,4 .               B)7 and 1,2,4,5

C)8 and 1,2,4,5 .               D)9 and 1,2,3,5
