A computer system with a word length of 32 bits has a 16 MB byte- addressable main memory and a 64 KB, 4-way set associative cache memory with a block size of 256 bytes. Consider the following four physical addresses represented in hexadecimal notation.

A1 = 0x42C8A4
A2 = 0x546888
A3 = 0x6A289C
A4 = 0x5E4880

Which one of the following is TRUE ?
A
A1 and A4 are mapped to different cache sets.
B
A2 and A3 are mapped to the same cache set.
C
A3 and A4 are mapped to the same cache set.
D
A1 and A3 are mapped to the same cache set.

Correct : b
