Match List I with List II

LIST I

(A) Har Gobind Khorana (B) C.V. Raman (C) Jagdish Chandra Bose (D) Aryabhata

LIST II

(I) Discovery of Zero (II) Genetic composition of cell (III) Scattering of light (IV) Measurement of plant growth

Choose the most appropriate answer from the options given below:

The correct answer is A-II, B-III, C-IV, D-I.

Let us understand the scientific achievements and contributions of each scholar listed in List I to match them correctly with List II:

(A) Har Gobind Khorana matches with (II) Genetic composition of cell:
Har Gobind Khorana was a pioneering biochemist who shared the 1968 Nobel Prize in Physiology or Medicine. His ground-breaking research helped decode the genetic code and demonstrate how the genetic composition of a cell (nucleic acids) directs the synthesis of proteins.

(B) C.V. Raman matches with (III) Scattering of light:
Sir Chandrasekhara Venkata Raman was an eminent physicist who was awarded the Nobel Prize in Physics in 1930. He discovered that when light traverses a transparent material, some of the deflected light changes wavelength. This phenomenon of inelastic scattering of light is widely known as the "Raman Effect".

(C) Jagdish Chandra Bose matches with (IV) Measurement of plant growth:
Sir Jagdish Chandra Bose was a polymath who made significant contributions to plant physiology. He invented the crescograph, a highly sensitive device capable of measuring microscopic variations in plant growth, proving that plants have a sensitive response to external stimuli.

(D) Aryabhata matches with (I) Discovery of Zero:
Aryabhata was an extraordinary mathematician and astronomer from classical Indian mathematics. His seminal works laid the foundational principles for the place-value system and the mathematical concept and usage of zero (known as 'shunya').

Combining these matches, we get:
A - II
B - III
C - IV
D - I
