Recipient’s private key

B.
Sender’s public key

C.
Recipient’s public key

D.
Sender’s private key

Explanation:
When the sender wants to send a message to the receiver, it’s important that this message not be altered. The
sender uses the private key to create a digital signature. The message is, in effect, signed with the private key.
The sender then sends the message to the receiver. The recipient uses the public key attached to the message
to validate the digital signature. If the values match, the receiver knows the message is authentic. Thus, the
recipient uses the sender’s public key to verify the sender’s identity.
