When the sender and receiver of an email are on the same system, we need only _____ user agents.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. two.
When both the sender and receiver of an email are on the same system, two user agents are needed. Each user agent manages different aspects of email communication, such as creating, sending, receiving, and organizing messages. Even though they are on the same system, each user requires their own user agent to handle their individual email processes. One user agent is responsible for sending the email, while the other handles receiving and viewing it, ensuring smooth email management for both users.
