Answer is B

Locality of reference is also called as principle of locality.  It means that same data values or related storage locations are frequently accessed.  This in turn saves time.  There are mainly three types of principle of locality:

1) temporal locality

2) spatial locality

3) sequential locality

This is required because in programs related data are stored in consecutive locations and in loops same locations are referred again and again
