The correct answer is: D. Vikram Ambalal Sarabhai
Vikram Ambalal Sarabhai (1898-1975) was an Indian scientist and industrialist who is considered to be the father of the Indian space program. He was born in Ahmedabad, Gujarat, and received his early education in the city. He then went on to study at the University of Cambridge, where he obtained a degree in physics. After graduating from Cambridge, Sarabhai returned to India and started working as a textile manufacturer. However, he soon became interested in science and technology, and he founded the Physical Research Laboratory (PRL) in Ahmedabad in 1947.
The PRL became a leading research center in India, and Sarabhai played a key role in the development of the country’s space program. He was also a pioneer in the field of nuclear energy, and he founded the Atomic Energy Commission of India in 1954. Sarabhai was awarded the Padma Vibhushan, India’s second-highest civilian award, in 1966. He died in 1975 at the age of 77.
