World Wide Web is being standard by

Answer: Option B

The correct answer is B: W3C
Let's break down why:

W3C stands for the World Wide Web Consortium.
This organization is the main international standards organization for the World Wide Web.
They develop and maintain the standards that ensure websites work consistently across different browsers and devices.

Why the other options are incorrect:
* A: Worldwide corporation: This is too general; no specific corporation oversees web standards.
* C: World Wide Consortium: While similar to W3C, the correct and officially recognized acronym is W3C.
* D: World Wide Web Standard: This is a description, not the name of the organization responsible.

Therefore, W3C is the definitive body responsible for standardizing the World Wide Web.
