Biomolecules are

Options

A. Inorganic materials
B. Organic materials
C. All the carbon compounds obtained from living tissues
D. Only DNA, RNA

Answer

### Step-by-Step Solution:

1. **Understanding Biomolecules**: Biomolecules are essential components of living organisms. They are primarily organic compounds that play critical roles in biological processes.

2. **Classification of Compounds**: Biomolecules can be categorized under two main types of compounds: inorganic and organic compounds. While inorganic compounds do exist in living organisms, biomolecules specifically refer to organic compounds.

3. **Examples of Biomolecules**: Common examples of biomolecules include carbohydrates, proteins, and lipids. Each of these plays a vital role in the structure and function of cells.

4. **Constituents of Biomolecules**: The primary elements that make up biomolecules are carbon (C), hydrogen (H), and oxygen (O). These elements combine in various ways to form the complex structures of biomolecules.

5. **Conclusion**: Based on the understanding that biomolecules are organic compounds made up of carbon, hydrogen, and oxygen, we can conclude that the correct answer to the question is that biomolecules are organic materials.

### Final Answer:
Biomolecules are organic materials.
