A1, 2 & 3 only

B1 & 3 only

C2 & 4 only

D1, 2, 3 & 4 ✓ Correct

Correct answer: (D) 1, 2, 3 & 4

Explanation

All four statements about the evolution of the Web are accurate, so every one of them is true.

Statement 1 is true because Web 2.0 is the participative social web built around user-generated content and interaction.

Statement 2 is true because Web 1.0 was the read-only web of static pages that users could only view.

Statement 3 is true because YouTube, wikis and blogs are leading Web 2.0 applications enabling sharing and collaboration.

Statement 4 is true because Web 3.0 is described as the read, write and execute web, adding intelligence and automation.

The correct choice therefore includes all four statements.

Web 3.0 is closely linked to the Semantic Web and machine-understandable data.
