The primary purpose of the <caption> tag within a table is to provide a description or summary of the content contained in that table. This tag is typically placed immediately after the opening <table> tag and serves to give context to the data presented, making it easier for users to understand the table’s purpose.

In terms of accessibility, the <caption> also helps assistive technologies convey the meaning of the table to users who may rely on screen readers. This additional information is especially useful when tables are complex or when users may not have immediate context for the data.

Other options, while related to tables, do not accurately describe the function of the <caption> tag. For example, while headers help define sections of a table, they are specified separately using the <th> tag, which is different from the role of the <caption> tag. Defining the table's layout is typically done through CSS or attributes within the table tags themselves. Inserting images into a table would involve using the <img> tag within a table cell and is not related to the purpose of the <caption> at all.
