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

A
$$P - N - lo{g_2}K$$
B
$$P - N + lo{g_2}K$$
C
$$P - N - M - W - lo{g_2}\,\,K$$
D
$$P - N - M - W + lo{g_2}\,\,K$$
