D Correct answer
Explanation

Pisces (fish) respire through gills, not lungs. Gills are specialized organs that extract dissolved oxygen from water as it flows over them. A streamlined body reduces water resistance for efficient swimming, and scaly skin provides protection. Most fish are oviparous (egg-laying). The statement 'Respire through lungs' is incorrect for fish and identifies the non-characteristic feature.
