To which of the following crops does the term 'ginning' apply?

The term "ginning" applies to the crop of cotton. Ginning is the process of separating the cotton fiber from the seeds and other debris that are harvested along with the cotton. The cotton gin, which was invented by Eli Whitney in the late 18th century, is the machine that performs this process. The cotton gin uses a combination of mechanical teeth and air flow to separate the cotton fibers from the seeds and other unwanted materials. After ginning, the cotton fibers are baled and sent to textile mills where they are spun into thread and fabric.
