What is Ci in the bit-by-bit XOR hash function, that is Ci = bi1 + bi2.….. + bim

A. Number of n bit blocks

B. Ith bit of the hash code

C. Ith bit in jth block
D. Xor operation

Explanation: “m” is the number of n-bit blocks in the input, bij is the ith bit in the jth block, ci is the ith bit of the hash code. Operation between the bits is exclusive OR and this operation is performed on every input block.
