Solution
The correct option is A Crustacea
- Crustaceans are animals that are characterized by the presence of hard exoskeletons, the segmented body which is bilaterally symmetrical.
- They do have sensory antennae and mandibles.
- Helically coiled shaped X-organ–sinus-gland complex is found in crustacea class located in the eyestalk.
- The X-organ passes its secretions to the sinus gland, which acts as a release centre into the blood. Hormones liberated from the sinus gland have been shown to influence molting, gonad development, water balance, blood glucose, and the expansion and contraction of pigment cells both in the general body and in the retina of the eye.
- Thus, Option A is correct.
