What is a distinguishing feature of the Jumping Spider?

The distinguishing feature of the Jumping Spider is its size, which typically ranges around 3/8 inch, and it often exhibits a red abdomen. This small size is a common trait of many jumping spiders, setting them apart from larger spider species.

This contrasts with other spiders that create webs for trapping. Therefore, the combination of their size and potential coloration, especially regarding the abdomen, makes option C the most accurate representation of a distinguishing feature of this spider.
