Correct option is A
Explanation:
Snakes (A) have heat-sensing pits (II) used to detect infrared radiation for prey detection.
Spiders (B) produce silk using spinnerets (IV) located on their abdomen.
Fishes (C) possess a lateral line (I) system to detect water movements and vibrations.
Dolphins (D) use echolocation (III) to navigate and hunt underwater.
Information Booster:
Heat sensing pits in snakes are specialized sensory organs enabling detection of warm-blooded prey.
Spinnerets in spiders are silk-spinning organs crucial for web construction and prey capture.
The lateral line system in fishes consists of mechanoreceptors sensitive to water flow and pressure changes.
Echolocation in dolphins involves producing sound waves and interpreting their echoes for spatial orientation.
