B) 14

Explanation: 
Type of mapping is direct map; for this direct map, 10 bits are required in itss Tag. 
It is updated to 16 way set Associative map then new tag field size = 10 + log216 = 14 bits, because for k way set associative map design, log2k bits are additionally required to the number of bits in tag field for Direct map design.
