The main purpose of classification of organisms is to

Options

A. study geography
B. locate plants and animals
C. establish relationship among organisms and study evolution
D. All are correct

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the main purpose of classifying organisms. Classification is a systematic way of organizing living things based on shared characteristics.

2. **Identifying the Options**: The options provided are:
- A) Study geography
- B) Locate plants and animals
- C) Establish relationships among organisms
- D) Study evolution
- E) All are correct

3. **Analyzing Each Option**:
- **Option A (Study geography)**: While geography may play a role in the distribution of organisms, it is not a primary purpose of classification.
- **Option B (Locate plants and animals)**: Locating organisms can be a result of classification but is not the main purpose.
- **Option C (Establish relationships among organisms)**: This is a significant purpose of classification as it helps in understanding how different organisms are related to one another.
- **Option D (Study evolution)**: Classification also aids in studying the evolutionary history of organisms, which is a critical aspect of biology.
- **Option E (All are correct)**: This option suggests that all the previous options are equally valid, which is not the case.

4. **Determining the Main Purpose**: The main purposes of classification are primarily to establish relationships among organisms and to study evolution. Therefore, the most appropriate answer from the given options is:
- **C) Establish relationships among organisms** and **D) Study evolution**.

5. **Final Answer**: Since the question asks for the main purpose and options C and D are closely related, we can conclude that the best answer is:
- **C) Establish relationships among organisms**.
