5. Alice uses a digital signature(DS) to communicate with Bob for authentication and integrity. Bob claims to have received a message in clear text, "Transfer $1432 to Peter," with a valid digital signature from Alice. Alice denies sending the message. The digital signature proves that Alice must have created the message. Select the correct Option:

A. True

B. False
