Find the incorrectly matched pair

Options

A. Die Naturlichen Pflanzen Familien -Engler and Prantl
B. Families of Flowering Plants -John Hutchinson
C. Flora of British India-Bentham
D. Philosophia Botanica-Principles of binomial nomenclature

Answer

To solve the question of finding the incorrectly matched pair of book titles and their respective authors, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**:
We have four options that pair book titles with their authors.

2. **Evaluate Each Option**:
- **Option 1**: "Dynaturalation Piflansenfamilion" by Engler and Pranty.
- This is correctly matched as Engler and Pranty are known authors of this work.

- **Option 2**: "Families of Flowering Plants" by John Hutchinson.
- This is also correctly matched; John Hutchinson is indeed the author of this book.

- **Option 3**: "Flora of British India" by Bentham and Hooker.
- This is correctly matched as Bentham and Hooker are the authors of this significant work.

- **Option 4**: "Philosophia Botanica" (the book name) and the principle of binomial nomenclature.
- This option is incorrectly matched because it does not provide the author's name (Carl Linnaeus) but instead mentions a principle related to the book.

3. **Conclusion**:
After evaluating all options, we find that Option 4 is the incorrectly matched pair since it fails to provide the correct author name for "Philosophia Botanica".

### Final Answer:
The incorrectly matched pair is **Option 4**.
