In a $$k$$-way set associative cache, the cache is divided into $$v$$ sets, each of which consists of $$k$$ lines. The lines of a set are placed in sequence one after another. The lines in set $$s$$ are sequenced before the lines in set $$(s+1).$$ The main memory blocks are numbered $$0$$ onwards. The main memory block numbered $$j$$ must be mapped to any one of the cache lines from
A
$${\left( {j\,\,\bmod \,\,v} \right)^ * }k\,\,$$ to $${\left( {j\,\,\bmod \,\,v} \right)^ * }k\, + \,\,\,\,\,\,\left( {k - 1} \right)$$
B
$${\left( {j\,\,\bmod \,\,v} \right)}\,\,$$ to $$\left( {j\,\,\bmod \,\,v} \right)\, + \,\left( {k - 1} \right)$$
C
$${\left( {j\,\,\bmod \,\,k} \right) }\,\,$$ to $$\left( {j\,\,\bmod \,\,k} \right)\, + \,\left( {v - 1} \right)$$
D
$${\left( {j\,\,\bmod \,\,k} \right)^ * }v\,\,$$ to $${\left( {j\,\,\bmod \,\,k} \right)^ * }\,v + \,\left( {v - 1} \right)$$
