Answer: D

Explanation:

Secure unsubscribe option for end users. Mimicking an unsubscribe option is a popular phishing

technique. For this reason, the end users are generally wary of clicking unknown unsubscribe links.

For such scenarios, the cloud-based Unsubscribe Service extracts the original unsubscribe URI,

checks the reputation of the URI, and then performs the unsubscribe process on behalf of the end

user. This protects end users from malicious threats masquerading as unsubscribe links.
