Difficulty: Easy
Correct Answer: New semantic elements, built in audio and video tags, canvas for 2D graphics, local storage APIs, and better form controls and input types.
Explanation:
Introduction / Context:
HTML5 is a major revision of the HyperText Markup Language that powers the web. It introduced many new elements and APIs aimed at building richer, more semantic, and more interactive web applications without relying heavily on third party plugins.

HTML5 also includes APIs for localStorage and sessionStorage, offline application caching (now largely replaced by Service Workers), and new form input types like email, url, number, and date, improving validation and mobile friendliness.
Step-by-Step Solution:
Verification / Alternative check:
Modern HTML5 tutorials and references highlight these same features as the key improvements of HTML5. Browser compatibility tables show native support for <audio>, <video>, <canvas>, and localStorage across contemporary browsers, confirming their status as core HTML5 additions.

Common Pitfalls:
Some developers think HTML5 is only about new tags, ignoring the powerful JavaScript APIs that arrived alongside it. Others misunderstand semantic tags and use them only for styling instead of conveying document meaning. Using the new features properly improves accessibility, SEO, and maintainability of web applications.
Final Answer:
The correct choice is New semantic elements, built in audio and video tags, canvas for 2D graphics, local storage APIs, and better form controls and input types. because this option accurately summarizes the major improvements introduced in HTML5.
