Silk originates from which source?

Silk originates from which source?

• A. Bees' wax glands
• B. Spiders' webs
• C. Cocoon (Silk Worm)
• D. Cotton boll fibers

Answer: (C)

Silk used in textiles comes from the cocoon spun by silkworms. During the larval stage, the silkworm secretes a protein fluid from its silk glands and spins a long, continuous filament that hardens into a cocoon around itself. This cocoon is the source of the silk fiber, which is reeled out to make thread. The other options relate to very different substances—beeswax from bees, spider silk produced by spiders (not cocoon-based), and cotton fiber from the cotton plant. So the cocoon of the silkworm is the correct origin.
