What characteristic distinguishes a broad cloth from other fabrics?

Broad cloth is distinguished from other fabrics primarily by its smooth, semi-gloss finish. This characteristic arises from the way broad cloth is woven, which results in a fabric that has a tightly woven structure giving it a sleek look and feel. While it can be relatively comfortable and durable, the semi-gloss surface not only makes it visually appealing but also adds to its use in formal attire and high-quality garments.

The other options describe characteristics that, while relevant to some textiles, do not specifically define broad cloth. For instance, certain fabrics might indeed have a ribbed pattern or a heavy weight, but these traits do not uniquely identify broad cloth. Similarly, while its luxurious appearance may be a result of the smooth finish, it is the specific semi-gloss texture that sets broad cloth apart from all others, making the correct answer particularly focused on this distinct surface quality.
