What is true for mammalia:
- Platypus is oviparous
- Bats have feather
Elephant is a ovoviviparous
- Diaphragm is absent in them
The Correct Option is A
Solution and Explanation
Mammals are defined by the presence of mammary glands, a muscular diaphragm, skin covered in hair, and typically giving birth to live offspring, with the notable exception of the platypus, which is an egg-laying mammal (oviparous).
So, the correct option is (A): Platypus is oviparous

Concepts Used:
Animal Kingdom
Animals are eukaryotic, multicellular species that belong to the Kingdom Animalia. Every animal has a distinct characteristic. They get energy either by feeding on plants or on other animals. There are millions of species that have been recognized, few shares similar characteristics while others vary drastically.
Kingdom Animalia comprises all animals. In the midst of the five kingdoms, the largest kingdom is the animal kingdom. Animals are multicellular eukaryotes. Though, like plants, they do not possess chlorophyll or a cell wall. Therefore, members of the animal kingdom indicate a heterotrophic mode of nutrition. Kingdom Animalia is further classified into ten different subphyla based on their body designs or differentiations.
The different phyla of the Kingdom Animalia are as follows:
- Porifera
- Coelenterata (Cnidaria)
- Platyhelminthes
- Nematoda
- Annelida
- Arthropoda
- Mollusca
- Echinodermata
- Hemichordata
- Chordata
