Choose the most appropriate answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A-II, B-III, C-IV, D-I
(A) Har Gobind Khorana — this matches (II) Genetic composition of cell. He shared the 1968 Nobel Prize in Physiology or Medicine for work on the genetic code, and later made the first artificial gene.
(B) C.V. Raman — this matches (III) Scattering of light. His discovery of 1928, the Raman effect, won him the Nobel Prize in Physics in 1930; 28 February is kept as National Science Day in its memory.
(C) Jagdish Chandra Bose — this matches (IV) Measurement of plant growth. He invented the crescograph, an instrument that records the very small growth and responses of plants.
(D) Aryabhata — this matches (I) Discovery of Zero. The 5th-century mathematician used the place-value system in his Aryabhatiya (499 CE) and is popularly credited with zero; the rules for working with zero as a number were first written down by Brahmagupta in 628 CE.
