Which of the following represents the correct combination of a taxonomic group with its characteristics, without any exception? Group Characteristics
1 Reptilia-Crawling mode of locomotion, all are terrestrial
2 Chondrichthyes-Placoid scales, electric organs, claspers
3 Amphibia-Tympanum, two pairs of limbs
4 Mammalia-Mammary glands, lungs, direct development
Explanation:
All mammals possess mammary glands, lungs and undergo direct development. Some reptiles are aquatic (e.g., sea snakes, turtles). Electric organs are present only in some cartilaginous fishes (e.g., Torpedo ); not all. Some amphibians are limbless (e.g., Ichthyophis).

3 All bony fishes have four pairs of gills and an operculum on each side.
4 All mammals are viviparous and possess diaphragm for breathing
Explanation:
Some freshwater sponges exist as well, for example, Spongilla. Some reptiles like crocodiles possess a 4 chambered heart. Mammals like Ornithorhyncus are oviparous.
