(B) Taxus baccata
(C) Nepenthes
(D) All of the above

Answer 1

Hint: The animals are said to be endangered if they are facing the high risk of extinction may be in the future. This may be due to the decrease in the habitat of the organisms, affected by the predators. The main reason for the extinction is loss of habitat and the genetic variation.

Complete Answer:
- The species get endangered mainly due to the loss of the habitat by the process of deforestation.
- Deforestation is defined as the process of cutting down the forest. If the wildlife habitat is destroyed, the animals don't get enough food and the water for their survival.
- Hence the count of the organisms goes on decreasing, resulting in the extinction of the species. The other reason for the species to become endangered is genetic variation.
- Rauwolfia serpentina is a type of blooming plant in the family Apocynaceae. It is local to the Indian subcontinent and East Asia.
- Rauwolfia serpentina is declining, because of their use in medicinal use. Taxus baccata is a type of the conifer which is local to western, northwest Africa, northern Iran and southwest Asia.
- It has more economic and therapeutic values than different gymnosperms. The anticancer substances found in the tree are valuable for human wellbeing. Nepenthes khasiana is a tropical pitcher plant of the sort Nepenthes. It is the main Nepenthes species local to India.

Thus the option (D) is correct.

Note: Some of the organisms become extinct due to many reasons like deforestation, forest fires etc. Hence the government of India has created many wildlife sanctuaries, national parks and the biosphere reserves to protect the wild life that goes on extinction.
