Organic compounds mainly contains

Options

A. C, H, O
B. C,O,N
C. N,C,S
D. C,P,N

Explanation

### Step-by-Step Solution:

1. **Understanding Organic Compounds**: Organic compounds are a large class of chemical compounds that primarily contain carbon atoms. These compounds can be simple or complex and are characterized by the presence of carbon.

2. **Key Elements in Organic Compounds**: The main component of organic compounds is carbon (C). However, organic compounds also contain other elements such as hydrogen (H), oxygen (O), nitrogen (N), sulfur (S), and phosphorus (P).

3. **Covalent Bonding**: In organic compounds, carbon atoms are covalently bonded to one another and to other elements. This means that they share electrons to form stable molecules.

4. **Common Combinations**: The most common elements found in organic compounds are carbon, hydrogen, and oxygen. When these elements are combined, they form various types of organic compounds, such as hydrocarbons (which contain only carbon and hydrogen) and alcohols (which contain carbon, hydrogen, and oxygen).

5. **Classification of Organic Compounds**: Organic compounds can be classified based on their structure and the elements they contain. For example, hydrocarbons are a type of organic compound that consists solely of carbon and hydrogen.

6. **Conclusion**: Therefore, the main elements that organic compounds primarily contain are carbon (C), hydrogen (H), and oxygen (O). This is often summarized as C-H-O.

### Final Answer:
Organic compounds mainly contain carbon (C), hydrogen (H), and oxygen (O).
