In HTML, heading tags are used to create headings and subheadings on a webpage, with their size and importance defined by the order of the tags. The hierarchy of heading tags runs from H1 to H6, where H1 is the largest and most important heading, typically used for the main title of a page, while H6 represents the smallest and least significant heading.

Choosing H6 as the smallest heading is correct because it is designated as the least important level in the heading hierarchy. As you move from H1 to H6, each subsequent tag indicates a decreasing level of prominence or size. H6 is ideal for providing structure to the content while still maintaining semantic meaning, often used for subsections within a document.

In contrast, H1, H3, and H5 are larger and represent higher levels of headings, with H5 being a smaller heading than H3 but still larger than H6. Thus, H6 is definitively the smallest heading tag, making it the correct answer.
