Step 1: Understanding Twill Weave.
Twill weave is identified by diagonal lines or ribs on the fabric surface.
It is created by passing the weft thread over one or more warp threads and then under two or more warp threads, shifting in each row.
This gives the fabric strength, flexibility, and a distinct diagonal pattern.
Step 2: Application in Serge.
Serge is a durable fabric used in uniforms and suits.
It always uses twill weave, showing clear diagonal ribs.
Step 3: Application in Gabardine.
Gabardine is a tightly woven twill fabric, usually made from wool or cotton.
It is known for durability and is commonly used in trousers and suits.
Step 4: Application in Tweed.
Tweed is a rough woolen fabric, almost always woven in twill patterns.
It often has multi-colored yarns and the diagonal twill lines are a signature.
Step 5: Application in Surah.
Surah is a lightweight silk twill fabric.
It has fine diagonal lines and is often used in dresses and scarves.
Step 6: Conclusion.
All four fabrics – Serge, Gabardine, Tweed, and Surah – use twill weave.
Hence, the answer is option 4 (A, B, C and D).
