Answer:
The correct answer is - uniramous.
Explanation:
The appendages are present on each body segment of all arthropods. Each segment generally has a pair of end to end appendages. The appendages of the arthropods may be either uniramous or biramous depending on their number of branches in segments.
Uniramous appendages are the appendages that comprise the single series of the end to end attached together, whereas biramous appendages have two branches and each branch has a series of the end to end segments.
Thus, the correct answer is - Uniramous appendages.
