Question

Match LIST-I with LIST-II
LIST-I (Atmospheric component)
(A) Nitrogen
(B) Sulphur dioxide
(C) Aerosols
(D) Ozone
LIST-II (Role)
(I) Hypnoxyotic an(t)icle
(II) Photochemical interaction
(III) Retards re-radiation... (Greenhouse Effect)
(IV) Acid rain

• A. A-III, B-II, C-I, D-IV
• B. A-I, B-III, C-II, D-IV
• C. A-III, B-IV, C-I, D-II
• D. A-IV, B-II, C-I, D-II

Hint:

When faced with a flawed matching question, identify the most certain and unambiguous pairs first. Then, scan the options to see which one contains those correct pairs. This process of elimination can often lead to the intended answer even if other parts of the question are incorrect.

Answer 1

The Correct Option is C

Step 1: Find the most definite matches.
- Sulphur dioxide (B) is a primary precursor to Acid rain (IV) when it reacts with water in the atmosphere. This is a strong, direct link. (B \(\rightarrow\) IV) - Tropospheric Ozone (D) is a key product and component of Photochemical interaction (II), which creates smog. This is also a strong link. (D \(\rightarrow\) II)

Step 2: Check the options for these pairs.
We are looking for an option that contains both B-IV and D-II. - Option (A) has B-II. Incorrect. - Option (B) has B-III. Incorrect. - Option (C) has B-IV and D-II. This is a potential match. - Option (D) has B-II. Incorrect.

Step 3: Evaluate the remaining matches in the potential option (C).
Option (C) suggests the complete matching: A-III, B-IV, C-I, D-II. - A (Nitrogen) \(\rightarrow\) III (Greenhouse Effect). This is incorrect. Nitrogen is not a significant greenhouse gas. - C (Aerosols) \(\rightarrow\) I (Hypnoxyotic...). The term in (I) is garbled and likely a typo. Despite the clear errors with A\(\rightarrow\)III and C\(\rightarrow\)I, option (C) is the only one that contains the two correct and unambiguous pairings (B\(\rightarrow\)IV and D\(\rightarrow\)II). Therefore, it is the intended answer, assuming errors in the other parts of the question.
