Which of the following join options will you choose to create a stroked line with squared corners?

To create a stroked line with squared corners, you should choose the "Miter Join" option. Here are the steps:

1. Open your design software (like Adobe Illustrator or Photoshop).
2. Select the Pen tool or Line tool to create a line.
3. Go to the Stroke panel.
4. Look for the option called "Corner" or "Join".
5. From the dropdown menu, select "Miter Join". This option creates squared corners.
6. Draw your line and you will see that it has squared corners.

Remember, the Miter Join option may create overly sharp corners if the angle of the turn is too small. You can adjust the miter limit in the Stroke panel to control the appearance of the corners.
