Correct option is D
Correct answer
Option d — A-ii, B-i, C-iv, D-iii
Explanation
A (Dorsal rim area) → ii (Polarization vision): The dorsal rim area of the compound eye contains specialized photoreceptors tuned to detect the e-vector of polarized light, used for skylight polarization navigation.
B (Mushroom body) → i (Learning and memory): Mushroom bodies are the higher-order neuropils in insects responsible for olfactory learning, memory formation and multimodal integration.
C (Antennal lobe) → iv (Mechanosensation): The antennal lobe is the primary antennal processing center. Although classically associated with olfaction, antennae also carry mechanosensory inputs that are processed by antennal pathways; in the context of the given options, antennal lobe → mechanosensory/antennal input processing is the best match.
D (Central complex) → iii (Motor control): The central complex is a midline brain structure that coordinates locomotion, steering and spatial orientation — key for motor control.
Information Booster
-Dorsal rim area: Critical for celestial navigation in many insects (bees, ants, locusts).
-Mushroom bodies: Integrate sensory input (especially olfactory) with experience-dependent plasticity; lesions cause deficits in associative learning.
-Antennal lobe: Contains glomeruli that receive primary antennal afferents; major role in odor coding and in processing antennal sensory modalities.
-Central complex: Involved in motor patterning, path integration and heading representation.
