Question

Full form of CNG is

Accepted Answer

The full form of CNG is "Compressed Natural Gas," which is correctly represented by Option 2. Here is a detailed explanation justifying why Option 2 is correct and why the other options are incorrect:

1. **Explanation for Option 2 (Compressed Natural Gas):**
   - Compressed Natural Gas (CNG) is a type of fuel that is primarily composed of methane gas. It is stored at high pressure, which allows it to be used as an alternative to gasoline, diesel, or propane. CNG is known for being a cleaner and more environmentally friendly fuel option, as it produces fewer pollutants and greenhouse gases compared to traditional fossil fuels. The compression process allows natural gas to be stored in a smaller volume, making it practical for use in vehicles and other applications.

2. **Why Option 1 (Common National Gas) is incorrect:**
   - "Common National Gas" is not a recognized term in the context of fuels or energy resources. There is no such entity or concept as Common National Gas in the industry. The term does not accurately describe the nature or characteristics of CNG.

3. **Why Option 3 (Common Natural Gas) is incorrect:**
   - While "Natural Gas" is a correct term, the addition of "Common" does not accurately describe CNG. Natural gas is a naturally occurring hydrocarbon gas mixture, but CNG specifically refers to natural gas that has been compressed for storage and use as a fuel. The term "Common Natural Gas" does not convey the specific process of compression that is essential to CNG.

4. **Why Option 4 (Certified Natural Gas) is incorrect:**
   - "Certified Natural Gas" is not a standard term used in the industry. While natural gas can be certified for quality or environmental standards, the term does not specifically refer to the compressed form of natural gas used as a fuel. CNG specifically denotes the compression process, which is not captured by the term "Certified Natural Gas."

In conclusion, Option 2, "Compressed Natural Gas," is the correct answer because it accurately describes the process and form of natural gas used as an alternative fuel. The other options do not correctly represent the concept of CNG.
