a.
Doubles

b.
Halves

c.
Increases by 1

d.

Answer:nswer. Since there are 16 bytes in a cache block, the OFFSET field must contain 4 bits (24 = 16). To determine the number of bits in the SET field, we need to determine the number of sets. Each set contains 2 cache blocks (2-way associative) so a set contains 32 bytes.
