Which statement about the <var> element is true?

• A. It denotes a variable in mathematical expressions or programming contexts
• B. It defines an inline quotation
• C. It creates a hyperlink
• D. It formats text as bold emphasis

Answer: (A)

The main idea tested is that the <var> element is used to denote a variable in mathematical expressions or programming contexts. This semantic purpose helps both readers and assistive technologies understand that the content represents a variable token, not ordinary text. It’s an inline element, so you can place it within a sentence, for example in a mathematical statement like f(<var>x</var>) = x^2, where the variable is clearly distinguished. While browsers often render <var> content in italics by default, the critical point is its label as a variable, which you can style with CSS if needed. It does not denote an inline quotation, it does not create a hyperlink, and it does not apply bold emphasis—that would be handled by elements designed for those roles. So, labeling a variable in math or programming contexts with the <var> element is the correct usage.
