. Which of the following does not yield wool
D: Woolly dog
Correct Option is: (D) Woolly dog
Wool is a fiber obtained from the hair or fur of animals like sheep, goats, angora rabbits, and camels.
The hair of woolly dogs does not provide wool, because their hairs can not be spun like the hairs of sheep or goats.
Wool acts as an insulator and keeps us warm during the winter season.
Wools are highly breathable, flexible, and elastic.
