The Mendelian principles of inheritance were rediscovered by

Options

A. Sutton and Boveri
B. Hugo de Vries, Tschermak and Correns
C. Lederberg and Tatum
D. Morgan

Explanation

To solve the question regarding who rediscovered the Mendelian principles of inheritance, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks who rediscovered the Mendelian principles of inheritance.

2. **Recall Mendelian Principles**: Mendelian principles were formulated by Gregor Mendel in the mid-19th century (1865-1866). He proposed three key laws of inheritance:
- Law of Dominance
- Law of Segregation
- Law of Independent Assortment

3. **Identify the Rediscovery**: Mendel's work was not recognized until the early 20th century when it was independently rediscovered by several scientists.

4. **List the Scientists**: The scientists who rediscovered Mendel's principles in 1900 were:
- Hugo de Vries
- Karl Correns
- Erich von Tschermak

5. **Evaluate the Options**: Now, we compare the options given in the question:
- Sutton and Boveri: Known for chromosomal theory of inheritance.
- Hugo de Vries, Karl Correns, and Erich von Tschermak: Correct option.
- Lederberg and Tatum: Known for work on bacterial recombination.
- Morgan: Known for work on genetic linkage.

6. **Select the Correct Answer**: Based on the evaluation, the correct answer is the option that includes Hugo de Vries, Karl Correns, and Erich von Tschermak.

### Final Answer:
The Mendelian principles of inheritance were rediscovered by **Hugo de Vries, Karl Correns, and Erich von Tschermak**.
