Block size = 32 bytes ( 5 bit need to represent it)
Number of lines = 215
4 way set associative
Number of sets = 213
24 bit will be represented as 6 ( TAG) + 13 (Number of set) + 5 (block)
Address given = (E4201F)16 i.e (1110 0100 0010 0000 0001 1111)2
First 6 bit will be use for tag i.e 1110 01 or 39 in hex
Next 13 bit will be used for set i.e 0100 in hex
option a is correct here
