Explanation

HTML5 is designed to be backward-compatible and inclusive, which means it supports all CSS versions - CSS1, CSS2, and CSS3 - making D the correct answer. Options A, B, and C are incorrect because each artificially excludes one or more valid CSS standards: A drops CSS1 and CSS2, B drops CSS1, and C drops CSS3 (which is the most modern and widely used standard). HTML5 never dropped support for older CSS versions; it simply added compatibility for newer ones alongside them.

Memory tip: Think of HTML5 as "the inclusive standard" - it was built to unify web technologies, not restrict them. If HTML5 supports the newest CSS, it certainly didn't abandon the older ones.
