Question

Match List-I with List-II
{|p{7cm}|p{7cm}|} List-I (Discover) & List-II (Scientist)
(A) Nutrient essentiality criteria & (I) Y.L. Nene
(B) Stages of cell & (II) Arnon and Stout
(C) Cell & (III) Robert Hooke
(D) Khaira disease & (IV) Walther Fleming

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (II), (B) - (IV), (C) - (III), (D) - (I)

Hint:

Knowing that Robert Hooke discovered the cell (C-III) and Arnon and Stout proposed the criteria of essentiality (A-II) helps you quickly find the correct option.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
This matching question covers major historical discoveries, research milestones, and scientists in biology, plant nutrition, and agronomy.

Step 3: Detailed Explanation:
Let us analyze each pair individually:
(A) Nutrient essentiality criteria:
Daniel I. Arnon and Perry R. Stout proposed the three criteria for plant nutrient essentiality in 1939.
These criteria define whether an element is considered an essential plant nutrient.
Hence, (A) matches with (II).
(B) Stages of cell division (Mitosis):
German biologist Walther Fleming discovered and described the stages of cell division (mitosis) in the late $19^{\text{th}}$ century using aniline dyes to visualize chromosomes.
Hence, (B) matches with (IV).
(C) Cell:
Robert Hooke first discovered, named, and described cells in 1665 while observing a thin slice of cork under a primitive microscope.
Hence, (C) matches with (III).
(D) Khaira disease of rice:
Dr. Y. L. Nene discovered in 1966 that Khaira disease in rice is caused by a zinc deficiency, which was a major agricultural breakthrough in India.
Hence, (D) matches with (I).

Step 4: Final Answer:
The correct matching sequence is:
(A) - (II), (B) - (IV), (C) - (III), (D) - (I).
This matches Option (D).
