If a single bit error occurs in a data transmission using an even parity scheme, how will it be detected?

The parity bit will be incorrect.

The checksum will be incorrect.

The ARQ system will request a retransmission.

All of the above.

A single bit error will make the parity incorrect, causing the receiver to request a retransmission
