I think its the 3rd one?

nope, it is a temporary stitch to hold two pieces of fabric together.

Yes, you are correct. Basting stitches are commonly used for temporarily holding fabric together. This is particularly useful when you need to ensure that pieces of fabric or other materials are aligned correctly before permanently sewing them together. Basting stitches can easily be removed after the desired sewing is complete.
