The animal kingdom is divided into different types of organisms each organism is unique in the mode of reproduction and parturition. The type of habitat affects the mode of giving birth of organisms. Some organisms are aquatic and some organisms are terrestrial and some are both.

Complete answer:
Now, let’s get an idea about all the above-mentioned options.
* Amphibious- An amphibian is referred to as a cold-blooded vertebrate animal that thrives inborn in water and respires with the help of gills. As the larva approaches its adult form through a process known as metamorphosis, the animal's lungs develop the ability to breathe, and the animal becomes terrestrial(can live on land). Frogs, toads, and salamanders include the most common examples of amphibians. These organisms are called amphibious organisms as they can live on both land and water.
* Oviparous- An oviparous creature is one that produces eggs, and the offspring incubate after being ousted from the body. Oviparous creatures consistently bring forth their young ones outside of their body. Numerous creatures of land and water, fowls, fish, and reptiles are oviparous and regularly make homes to secure their eggs. This can be differentiated to ovoviviparous creatures, which incubate eggs within their bodies, at that point must live youthful. This can be found in certain sharks, snakes, and different creatures.
* Triploblastic- When an animal develops the three body layers are formed from the embryonic layers which further forms the different parts of the body of an organism. The organism possessing all these three embryonic layers- Ectoderm, Mesoderm, and Ectoderm is called a triploblastic organism. Eg- Human beings.
* Viviparous- A reproductive process in which the organisms directly give birth to the young ones and the nutrition is provided inside the body through the placenta. Eg- Almost all mammals.

Animals that give birth to young ones are termed as Viviparous organisms. So, option (D) is correct.

Note: Exceptions are always there. For example, not all fishes are oviparous but some like sharks are ovoviviparous. The egg is also known as ovum, hence the animals which lay eggs, are termed as oviparous. On the contrary, viviparos are those which do not lay eggs.
