Correct Answer: A
Detailed Solution
The eminent astrophysicist J. V. Narlikar (Jayant V. Narlikar) strongly emphasised scientific temper and evidence-based reasoning and did not accept Astrology as a science.
In science, a hypothesis or prediction must be tested through observation, experiment and verifiable evidence. Such claims must be capable of being accepted, modified or rejected in the light of new evidence.
Astronomy is the scientific study of celestial objects and phenomena, while Cosmology scientifically studies the origin, structure and evolution of the Universe.
Nanotechnology is a field of Science and Technology concerned with the properties of matter at the nanoscale and their technological applications.
