Suggested answer: B

Explanation:

An email digital signature will verify to recipient the integrity of an email message because it ensures that the message has not been altered or tampered with during transit, and confirms that the message originated from the sender and not an imposter. An email digital signature will not protect the confidentiality of an email message because it does not encrypt or hide the message content from unauthorized parties. An email digital signature will not automatically correct unauthorized modification of an email message because it does not change or restore the message content if it has been altered or tampered with. An email digital signature will not prevent unauthorized modification of an email message because it does not block or stop any attempts to alter or tamper with the message content.
