Two computers that communicate with each other use a simple parity check to detect errors for ASCII transmissions. Which of the following events will always lead to an undeleted error?

A one bit or any odd number of bits inverted in a block of data during transmission
B two bits or any even number of bits inverted in a block during transmission
C one bit or any odd number of bits inverted in a byte during transmission
D two bits or any even number of bits inverted in a byte during transmission
E None of the above

Correct Answer: two bits or any even number of bits inverted in a byte during transmission
