Given below are two statements:
Statement I: An allotrope of oxygen is an important intermediate in the formation of reducing smog
Statement II : Gases such as oxides of nitrogen and sulphur present in troposphere contribute to the formation of photochemical smog. In the light of the above statements, choose the correct answer from the options given below:

Options

A. Both statement 1 and Statement Il are false
B. Statement I is true but Statement II is false
C. Both Statement I and Statement II are true
D. Statement I is false but Statement II is true

Answer

To solve the question, we need to analyze both statements given in the question regarding smog and the role of different gases and allotropes of oxygen.

### Step-by-Step Solution:

1. **Understanding Statement I**:
- Statement I claims that an allotrope of oxygen is an important intermediate in the formation of reducing smog.
- The allotrope of oxygen referred to here is likely ozone (O₃). However, ozone is primarily associated with photochemical smog, not reducing smog. Reducing smog is typically associated with sulfur dioxide (SO₂) and particulate matter from combustion processes. Therefore, this statement is **false**.

2. **Understanding Statement II**:
- Statement II states that gases such as oxides of nitrogen and sulfur present in the troposphere contribute to the formation of photochemical smog.
- Photochemical smog is formed when sunlight reacts with nitrogen oxides (NOₓ) and volatile organic compounds (VOCs), leading to the formation of ozone at ground level. While oxides of nitrogen do contribute to photochemical smog, sulfur oxides (SOₓ) are more associated with reducing smog. Therefore, since sulfur oxides are mentioned incorrectly in the context of photochemical smog, this statement is also **false**.

3. **Conclusion**:
- Both statements are false. Thus, the correct answer to the question is that both Statement I and Statement II are false.

### Final Answer:
Both Statement I and Statement II are false.
