The question was posed to me in examination.

The origin of the question is Traditional HTML and XHTML topic in section HTML Fundamentals of HTML

Answer 1

The correct answer is (b) Charset in both html and xhtml is “text/html”

To elaborate: HTML is case insensitive while XHTML is case sensitive. In XHTML, special characters can be escaped using character entites but not in HTML. Charset in HTML is “text/html” where as it is “application/xml+xhtml” for XHTML.
