Final Answer

The Bootstrap grid system allows for 12 columns across the page. Therefore, the correct answer is B) 12.

Explanation

Bootstrap's grid system is based on a 12-column layout, which provides significant flexibility in web design. This approach allows developers to create responsive layouts that adapt to various screen sizes and device types. By subdividing the 12 columns, you can create multiple combinations of column widths to suit content needs. For instance, you could use one full-width column (12), two equal-width columns (6 and 6), or three equal-width columns (4, 4, 4). This grid system plays a crucial role in responsive design, where content should adapt and reflow as the screen size changes, maintaining aesthetic and functional integrity across different devices.
