Fabrics characterized by having short fibers that create texture are referred to as having "nap." Nap is a term used primarily to describe fabrics that have a raised surface or pile, which can be made from short fibers. This raised texture can be felt and can vary in length, but the key feature is that the fibers are oriented in a way that gives the fabric a soft, textured feel. Common fabrics that exhibit nap include velvet, velour, and plush materials, all of which feature that tactile quality created by short, dense fibers.

The other choices do not fit this characteristic: velvet, while it is indeed a fabric with a nap, specifically refers to the type of material rather than the general characteristic of having short fibers. Silk is a smooth and lustrous fabric made from long fibers and generally does not possess the same texture that short fibers provide. Canvas, on the other hand, is a sturdy fabric typically made from tightly woven fibers that are not short and textured in the same way. Thus, "nap" is the term specifically addressing the texture created by short fibers.
