Here 64 encoding is asked so make group of 6 bits because 2^6=64
First group 101000 it corresponds to 40 which is o
Second group 110011 it corresponds to 51 which is z
third group 011111 it corresponds to 31 which is f
fourth group 101001 it corresponds to 41 which is p
fifth group 101010 it corresponds to 42 which is q Hence ozfpq D is the answer
