D. Dr. A. P. J. Abdul Kalam

Answer 1

Hint:In order to solve this you have the basic knowledge of plant science. You should also have the knowledge of all the scientists that are given in the question. Plant science which is also known as botany is the study of plants in all their forms using a scientific approach.

Complete step by step solution:
Sir Jagadish Chandra Bose was a botanist, biologist, physicist, and also a writer of science fiction. He made significant contributions to plant science and also has a major role in microwave optics and radio. He also invented a device named crescograph that helps in measuring the growth of plants. He has a major contribution in the field of biophysics, where he demonstrates the conduction of various stimuli in plants and also their electric nature.
Har Gobind Khorana was an Indian American biochemist. He got a Nobel prize in medicine in the year 1968 for the research that showed the order of nucleotides in nucleic acids, which control the cell’s synthesis of proteins and also carry the genetic code of the cell.
Homi Jehangir Bhabha was an Indian nuclear physicist and also a professor of physics and the founding director at the Tata Institute of Fundamental Research. He is also known as the father of the Indian nuclear program.
Dr. A. P. J. Abdul Kalam was an Indian aerospace scientist and he also served as the 11^th President of India. He worked as a scientist in the Defence Research and Development Organisation (DRDO) and also in the Indian Space Research Organisation (ISRO) and was also involved in military missile development efforts. Thus, he is also known as the Missile Man of India for his work and development in ballistic missiles.

Therefore, the correct option is (A) Jagadish Chandra Bose.

Note:Plant science is also known as Botany, this is a Greek word which means pasture or fodder. It involves the study and observation of plant growth and characteristics of plants and also investigates the relationship between the environment and plants.
