The correct option is B Angora rabbit
Angora hair or Angora fibre refers to the downy coat produced by the Angora rabbit. Angora is known for its softness, thin fibres, and what knitters refer to as a halo (fluffiness). It is also known for its silky texture. It is much warmer and lighter than wool due to the hollow core of the Angora fibre. It also gives them their characteristic floating feel.
