UDP and TCP use 1s complement for their checksum. Suppose you have the following two 8-bit bytes: 0101, 1010. What is the 1s complement of the sum of these 8-bit byte transmission with the checksum as follows: 1001, 0110. Can the checksum be used to detect the alteration?

A) 0000, no - cannot detect

B) 1111, no - cannot detect

C) 0000, yes - can detect

D) 1111, yes - can detect

E) No correct answer
