What kind of insects are Scorpions closest related to?

Scorpions are classified as arachnids, which is a key reason why this answer is correct. Arachnids make up a class of joint-legged invertebrates that include spiders, mites, ticks, and scorpions themselves. They are characterized by having eight legs, the absence of antennae, and a body divided into two main parts: the cephalothorax and the abdomen.

Understanding scorpions' relationship to arachnids helps clarify their biological and ecological significance. Like other arachnids, scorpions have specialized adaptations, including venomous stingers used for prey capture and defense. This classification reflects their evolutionary lineage, which is distinct from insects (such as flies, beetles, and lepidopterans), which belong to a different class within the arthropods.

The other options represent different classes of insects or insect-like organisms, and while they share a common ancestor with arachnids in the broader phylum Arthropoda, they are not closely related in an evolutionary sense. This context reinforces the understanding that scorpions, as arachnids, belong to a specialized group with specific features that set them apart from other insect categories.
