To create a bold heading, which of the following tags would you use?

To create a bold heading, using the tag is an effective choice because it not only emphasizes the text but also conveys that the text is of greater importance. In HTML, the tag is semantically meaningful, meaning it indicates to both the browser and search engines that the content within this tag is significant. As a result, it is styled in a bold manner by default in most browsers, achieving the visual effect desired for a bold heading.

While the

tag is used for creating headings and it appears bold by default as part of its styling, it is primarily intended for denoting document structure rather than just creating bold text. The tag also makes text bold, but it does not convey any additional meaning about the importance of the content. Lastly, the

tag is used for quoting sections of text, and does not apply to creating bold text or headings specifically. Thus, the tag is the best option for achieving both bold styling and semantic value.
