Answer 1

Hint: Chelicerata is a large group of aggressive arthropods belonging to the phylum of Arthropods. Some of them have been found to possess venom.

Complete answer: Chelicerata is a group under the phylum of Arthropoda. Like all arthropods, they are characterized by the segmented body and jointed appendages. The body of the organisms belonging to this group is divided into two parts namely, the cephalothorax and the abdomen.
The cephalothorax is formed by the fusion of the head and the thorax. There are 6 pairs of appendages and each pair is attached to the six segments of the cephalothorax. They have a characteristic claw-like structure called chelicerae, which act as a sensory organ and help in defense and feeding.
Arthropods like spiders, ticks, and scorpions all belong to this group whereas termites belong to the subphylum Hexapoda.
Given below is the diagram of spider which is one of the most common chelicerates:

Therefore, the correct answer is option D. Termite.

Note: Chelicerates living in a marine habitat have gills, and the air-breathing forms generally have both book lungs and tracheae.
