Euro norms and Bharat stages were given in new auto fuel policy for steadily reducing the ________ in petrol and diesel.

Options

A. Sulphur and particulate matter
B. Sulpur and `O_(3)`
C. Sulpur and aromatic contents
D. Aromatic contents and `NO_(x)`

Answer

To solve the question regarding what Euro norms and Bharat stages were given in the new auto fuel policy for steadily reducing in petrol and diesel, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Euro Norms and Bharat Stages**:
- Euro norms refer to the European standards for vehicle emissions, which set limits on the amount of pollutants that can be emitted by vehicles.
- Bharat Stage (BS) refers to the Indian standards that are similar to Euro norms, aimed at controlling the air pollution by regulating the output of air pollutants from internal combustion engines.

2. **Identify the Pollutants**:
- The question provides four options:
- a) Sulphur and particulate matter
- b) Sulphur and O3 (ozone)
- c) Sulphur and aromatic contents
- d) Aromatic contents and NO2 (nitrogen dioxide)

3. **Analyze the Options**:
- Euro norms and Bharat stages primarily focus on reducing harmful emissions from vehicles.
- Sulphur is a significant pollutant found in fuels, and reducing its content is crucial for improving air quality.
- Aromatic compounds in fuels are also harmful and contribute to air pollution.

4. **Select the Correct Answer**:
- Given the context of the question and the focus of both Euro norms and Bharat stages on reducing emissions, the most relevant pollutants to be reduced in petrol and diesel are **sulphur and aromatic contents**.
- Therefore, the best answer is: **sulphur and aromatic contents**.

### Final Answer:
Euro norms and Bharat stages were given in the new auto fuel policy for steadily reducing the **sulphur and aromatic contents** in petrol and diesel.
