The correct answer is D. Savitri.
Aurobindo Ghose (1872-1950) was an Indian nationalist, philosopher, yogi, and guru. He is best known for his contributions to Indian philosophy and spirituality, and for his work on the development of Integral Yoga.
Savitri is a long poem that Aurobindo wrote over a period of 20 years. It is considered to be his magnum opus, and is one of the most important works of Indian literature. The poem tells the story of the soul’s journey to self-realization, and is a profound exploration of the nature of God, love, and consciousness.
The other options are all books that Aurobindo wrote, but they are not as well-known as Savitri. Discovery of India is a historical and philosophical work that explores the history and culture of India. Hindu view of life is a collection of essays on Hindu philosophy. Yogashastra is a treatise on yoga.
