Question

Assertion (A): SMTP is used by the receiver to download emails from the mail server.
Reason (R): POP3 is a protocol designed for retrieving emails from a remote server to a local client.

• A. Both A and R are True, and R correctly explains A.
• B. Both A and R are True, but R does not correctly explain A.
• C. A is True, but R is False.
• D. A is False, but R is True.

Hint:

SMTP sends mail. Which protocol is used to fetch it?

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
Both statements are about email protocols. We check what each protocol does.

Step 2: Check the Assertion (A):
SMTP (Simple Mail Transfer Protocol) is used to send emails from the sender to the mail server and between mail servers. It is not used by the receiver to download mail. So A is FALSE.

Step 3: Check the Reason (R):
POP3 (Post Office Protocol version 3) is used by an email client to retrieve mail from the server to the local computer. So R is TRUE.

Step 4: Check option A and option B:
Both say A is true. A is false, so options A and B are wrong.

Step 5: Check option C:
It says R is false. R is true, so option C is wrong.

Step 6: Check option D:
It says A is false but R is true. This matches. So option D is right.

Final Answer:
A is false and R is true, so the correct option is D. \[ \boxed{\text{D. A is False, but R is True.}} \]
