What distinguishes the <strong> tag from the <b> tag?

The tag is used to indicate that the text it wraps has strong importance. Its primary role is to convey semantic meaning, which means it communicates to both the browser and the reader that the enclosed content has greater significance. This can positively impact accessibility, as screen readers may emphasize the text wrapped in a tag differently, ensuring that users understand its importance in context.

On the other hand, the tag does not provide any semantic meaning. It is purely a stylistic choice that simply renders text in bold without imparting any additional significance. This means that while both tags visually bolden text in a web page, only the tag enriches the document's meaning and context. Thus, the distinction lies in the capability of the tag to add value beyond mere presentation, making option A the correct choice.
