The correct answer is: A. Pen : Cap
A border is a line that separates two areas. A cap is a covering for the top of a pen. The cap protects the pen tip and keeps the ink from drying out.
The other options are incorrect because:
- A book has a cover, not a border. The cover protects the pages of the book and keeps them from getting damaged.
- A handle has a grip, not a border. The grip helps you to hold the handle and use it more easily.
- A frame has a mat, not a border. The mat protects the picture and keeps it from getting damaged.
I hope this helps!
