Which action describes the interlocking of upper and lower threads to create a stitch?

• A. Running stitch
• B. Backstitch
• C. Stitch formation
• D. Lockstitch

Answer: (C)

The action described is stitch formation. This is the process by which the needle carries the upper thread and the bobbin thread from below interlock to form a single stitch that holds the fabric together. It’s the act of creating the interlock itself, not just the type of stitch or a technique used to secure ends. A running stitch is a simple pass of the needle without an intentional interlock between the two threads, backstitch is about reinforcing or securing the seam by stitching backward, and lockstitch refers to the resulting stitch made by the interlocking threads, but the question focuses on the forming action that creates that interlock.
