Which data received causes a parity error? Suppose the data format is $1$ start bit, $8$ data bits, $1$ parity bit, and $1$ stop bit. The parity checker is based on odd parity.

Choice $1$ of $4$:$10101010,$ parity $=1$

Choice $2$ of $4$:$00000000,$ parity $=1$

Choice $3$ of $4$:$11110000,$ parity $=0$

Choice $4$ of $4$:$11111111,$ parity $=1$
