The correct Answer is:
To solve the question, we need to evaluate each of the three statements provided and determine if they are correct.
### Step-by-Step Solution:
1. **Evaluate Statement I: Natural gas is used for the manufacture of fertilizers.**
- Natural gas is primarily composed of methane and is a significant source of hydrogen. It is used in the Haber process to produce ammonia, which is a key ingredient in fertilizers. Therefore, this statement is **correct**.
2. **Evaluate Statement II: Petrochemicals are used in the manufacture of detergents.**
- Petrochemicals are derived from crude oil and are used to produce various chemical products, including synthetic detergents. Alkyl benzene, a type of petrochemical, is commonly used in the production of detergents. Hence, this statement is also **correct**.
3. **Evaluate Statement III: Naphthalene balls are obtained from coal tar.**
- Naphthalene is indeed derived from coal tar, which is a byproduct of the carbonization of coal. Naphthalene balls, often used as mothballs, are made from this aromatic hydrocarbon. Thus, this statement is **correct**.
### Conclusion:
All three statements are correct.
### Final Answer:
The correct answer is **Option 4**: All statements are correct.
