Using CBC$-$mode encryption with an $8-$byte $(64-$bit$)$ block cipher, a sender encrypts the

$8-$byte message "sendme$$2"($encoded in ASCII$),$ resulting in ciphertext $0$xAE EE $135$B $8$C $93$

$810639$ D$0815$A $07791743.$ Which of the following ciphertexts will decrypt to the message

"sendme$$6"?$

a$.0$xAE EE $135$B $8$C $93810639$ D$0815$A $07791745$

b$.0$xAE EE $135$B $8$C $93810039$ D$0815$A $07791743$
