Which fibers come from the Kashmir goat and are known for their softness and fine texture?

The fibers that come from the Kashmir goat are specifically known as cashmere fleece, which is highly prized for its exceptional softness and fine texture. Cashmere is a luxurious material that provides warmth while remaining lightweight, making it a preferred choice in high-end textiles and fashion.

In contrast, while alpaca fleece (which comes from the alpaca, a domesticated species of South American camelid) is also soft and warm, it is not derived from the Kashmir goat. Therefore, the correct answer highlights cashmere specifically, along with alpaca fleece, emphasizing the characteristics associated with both luxurious fibers. The other options include fibers that, while valuable in their own right, do not correspond to the Kashmir goat.
