Question

Match List-I with List-II

List-I (Event)	List-II (Occurrence)
(A) Carcinogenic	(I) Promoting cancer
(B) Pollution	(II) Photochemical smog
(C) Eutrophication	(III) Cell
(D) Gene	(IV) Over application of fertilizer

Choose the correct answer from the options given below.

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

Hint:

Matching the well-known link between eutrophication and fertilizer runoff (C to IV) allows you to quickly narrow down the options.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept: 
This matching question connects environmental and biological processes with their direct causes or occurrences. 

Step 2: Detailed Explanation: 
- (A) Carcinogenic matches with (I) Promoting cancer: Carcinogens are physical, chemical, or biological agents that promote cancer in living tissues. 
- (B) Pollution matches with (II) Photochemical smog: Photochemical smog is a form of air pollution produced by reactions between sunlight, nitrogen oxides, and volatile organic compounds. 
- (C) Eutrophication matches with (IV) Over application of fertilizer: Runoff containing excess nitrogen and phosphorus fertilizers drives algal blooms in nearby water bodies. 
- (D) Gene matches with (III) Cell: Genes are the basic physical and functional units of heredity located on chromosomes inside the cell nucleus. 
This sequence matches Option 

Step 3: Final Answer: 
The correct match is (A) - (I), (B) - (II), (C) - (IV), (D) - (III).
