Thanks that's what I thought but I just wanted to make sure before I turned it in.

To determine which of the following options is the most complete and accurate definition of fiber, let's analyze each choice:

A: A stringy substance from plants.
This definition accurately describes natural fibers like cotton or linen, which are obtained from plants.

B: The hair of an animal.
While this definition applies to some types of fibers like wool or silk, it is not inclusive of all types of fibers.

C: Man-made threads and yarns.
This definition refers to synthetic fibers, which are indeed man-made. However, not all fibers are man-made, so this definition does not encompass all types of fibers.

D: Basic raw material from which fabric is made.
This definition is the most complete and accurate because it includes both natural and synthetic fibers. Fibers are indeed the basic raw material from which fabrics are made.

Therefore, the most complete and accurate definition of fiber is option D: Basic raw material from which fabric is made.
