Solution
The correct option is E Pseudoscorpiones
Pseudoscorpions are a group of generally small arachnids (adults typically 0.5 to 5 mm long) that resemble those of scorpions. As their name suggests, they resemble miniature scorpions without a long stinging tail. The body of a pseudoscorpion has two distinct regions: the anterior cephalothorax and the posterior abdomen. The cephalothorax is covered dorsally by a sclerotized shield (carapace) and bears all the appendages. The segmented abdomen is oval or elongated in shape, rounded, and broadly connected to the cephalothorax. Each of the abdominal segments is covered dorsally by a sclerotized plate. The abdomen has no appendages.
