Question

For what does the W3C provide tutorials?

standardized domains
standardized plain text
standardized browsers
standardized HTML code​

Answer 1

standardized browsers

standardized plain text

standardized HTML code​

Step-by-step explanation:

W3C standardizes web technologies. Now the domain is part of networking, and has nothing to do with the web. Also, browsers, plain text and HTML codes are part of the web technologies and hence are covered by W3C.
