Answer

To determine which statement is incorrect regarding earthworms, we will analyze each statement provided in the question step by step.

### Step-by-Step Solution:

1. **Identify the Characteristics of Earthworms**:
- Earthworms are hermaphrodites, meaning they possess both male and female reproductive organs.

2. **Examine the First Statement**:
- The first statement claims that there are two pairs of testes located in the 10th and 11th segments.
- This statement is **correct** because earthworms do indeed have testes in these segments.

3. **Examine the Second Statement**:
- The second statement mentions that ovaries are present in the intersegmental septum of the 12th and 13th segments.
- This statement is also **correct** as the ovaries are located in these segments.

4. **Examine the Third Statement**:
- The third statement discusses the process of cross-fertilization between two earthworms.
- This statement is **correct** since, despite being hermaphrodites, earthworms typically engage in cross-fertilization with another individual.

5. **Examine the Fourth Statement**:
- The fourth statement claims that the male genital pore is present in the 14th segment.
- This statement is **incorrect** because the male genital pore is actually located in the 15th segment, while the female genital pore is found in the 14th segment.

### Conclusion:
The incorrect statement regarding earthworms is the fourth one, which incorrectly identifies the location of the male genital pore.
