Solution
The correct option is B a, b and e are true, c and d are false.
- Torpedo or electric ray has electric organs that are used to generate electric shock to paralyze the prey.
- Bony fishes use all the 5 kinds of fins for swimming.
- Amphibians do have moist skin but they do not have scales on their body.
- Birds are homeothermic and not poikilothermic because the can maintain temperature homeostasis.
- All mammals produce milk from mammary glands to nourish their young ones.
- So the correct answer is option B- 'a, b and e are true, c and d are false.'
