Protein can be most easily removed from

Options

A. Alkanes
B. Alkenes
C. Alkynes
D. Benzene

Explanation

To solve the question of where proteins can be most easily removed from, we need to analyze the solubility of proteins in the given substances: alkenes, alkynes, and benzene.

### Step-by-Step Solution:

1. **Understanding Protein Solubility**:
- Proteins are large biomolecules that can have varying solubility depending on the solvent. Generally, proteins are soluble in polar solvents (like water) but are insoluble in non-polar solvents.

2. **Analyzing the Given Options**:
- **Alkenes**: These are unsaturated hydrocarbons that are generally non-polar. Proteins are likely to be insoluble in alkenes.
- **Alkynes**: Similar to alkenes, alkynes are also non-polar hydrocarbons. Proteins would also be insoluble in alkynes.
- **Benzene**: Benzene is a non-polar solvent as well. Proteins are typically insoluble in benzene.

3. **Identifying the Best Option**:
- Since proteins are insoluble in all three options (alkenes, alkynes, and benzene), we need to determine which one allows for the easiest removal of proteins.
- Among these, benzene is a common non-polar solvent used in laboratory settings, and proteins can precipitate out of solution more readily in benzene due to its non-polar nature.

4. **Conclusion**:
- Therefore, proteins can be most easily removed from benzene because they do not dissolve in it, allowing for easier separation.

### Final Answer:
Proteins can be most easily removed from benzene.
