b. tcp/ip
c. dns
d. html

The correct answer to the following question will be C. DNS.

Explanation:

DNS stands for Domain Name System, users able to find any information with the help of the domain name. Each and every device which are connected to the internet has there owned IP address, DNS is a system used to translate the domain names into the IP address so it will find the information or browsers can load the resources of the internet.
