Which HTML tag is used to create a header cell in a table?

• A. <td>
• B. <th>
• C. <thead>
• D. <tr>

Answer: (B)

Header cells in an HTML table are created with the <th> element. The <th> tag marks a cell as a header, which helps browsers and assistive technologies understand the table's structure. It typically renders in a bold, centered style by default and improves accessibility by signaling to screen readers that the cell acts as a header for its column or row. Data cells use <td>, which holds regular content, while <tr> is simply a row that can contain either header or data cells. You might group header rows with <thead>, but the actual header cells are defined with <th> inside a row. Because of its semantic meaning and default accessible behavior, <th> is the correct choice for header cells.
