D. FTP	IV. Transfers files over the Internet

Choose the correct answer from the options given below:

The correct answer is A-III, B-II, C-I, D-IV.

Let us break down the function of each Internet Protocol listed in List - I and match it with the correct Internet Activity in List - II step-by-step:

1. A. HTTP matches with III. Sends TCP/IP packets to web server
HTTP (Hypertext Transfer Protocol) is the foundation of data communication for the World Wide Web. When you request a webpage, HTTP is used to structure the requests and responses, transmitting these messages as TCP/IP packets between your browser (client) and the destination web server.

2. B. SSL matches with II. Encrypts data for online transmission
SSL (Secure Sockets Layer) is a security protocol designed to establish encrypted links between a web server and a browser. It ensures that all data transmitted online remains private and protected from eavesdropping or tampering.

3. C. SMTP matches with I. Sends email through the Internet
SMTP (Simple Mail Transfer Protocol) is the standard protocol used specifically for sending and routing email messages across the Internet from a client application to an email server, or between different mail servers.

4. D. FTP matches with IV. Transfers files over the Internet
FTP (File Transfer Protocol) is a network protocol dedicated specifically to uploading, downloading, and transferring files between a client and a server over a TCP/IP network.

Combining these correct individual matches, we get:
A - III
B - II
C - I
D - IV
