Final answer:
Blowing (option a) is the technique that does not use fibers; it is related to glass-making, whereas basketry, sewing, and weaving are all fiber-based techniques used in textile production and the creation of various art forms.
Step-by-step explanation:
The type of artistic technique that does not use fibers is a. Blowing. Unlike basketry, sewing, and weaving which are all techniques involved in the creation of textiles or art using fibers, blowing refers to a glass-making process. Blowing involves shaping molten glass by blowing air into it through a tube known as a blowpipe, and it is not connected to textile production.
Basketry is the art of making vessels or containers by weaving together materials like wicker or reed. Sewing is the technique of stitching materials together with a needle and thread. Weaving is a textile production method that involves interlacing two sets of yarn or threads at right angles to each other—the warp and the weft—to create a fabric.
