Laws of inheritance were given by:

Options

A. Mendel
B. Darwin
C. Khorana
D. Lamarck

Answer

To solve the question "Laws of inheritance were given by:", we will analyze the options provided and identify the correct answer step by step.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- A) Mendel
- B) Darwin
- C) Khurana
- D) Lamarck

2. **Analyze Option A - Mendel**:
- Gregor Johann Mendel is known as the father of genetics. He conducted experiments on pea plants and formulated the laws of inheritance.
- The three main laws he proposed are:
- **Law of Dominance**: In a heterozygote, one trait will conceal the presence of another trait for the same characteristic.
- **Law of Segregation**: During the formation of gametes, the alleles for a trait segregate from each other so that each gamete carries only one allele for each trait.
- **Law of Independent Assortment**: Genes for different traits can segregate independently during the formation of gametes.
- Therefore, Mendel is indeed the correct answer for the laws of inheritance.

3. **Analyze Option B - Darwin**:
- Charles Darwin is famous for his theory of natural selection, which explains evolution. However, he did not propose any laws of inheritance. Thus, this option is incorrect.

4. **Analyze Option C - Khurana**:
- Dr. Hargobind Khurana is known for his work on the genetic code and was awarded the Nobel Prize for his contributions to understanding how genes work. He did not propose laws of inheritance. Therefore, this option is also incorrect.

5. **Analyze Option D - Lamarck**:
- Jean-Baptiste Lamarck is known for his theory of evolution, specifically the theory of acquired characteristics. He did not propose laws of inheritance. Thus, this option is incorrect as well.

6. **Conclusion**:
- After analyzing all options, the correct answer is **A) Mendel**.

### Final Answer:
The laws of inheritance were given by **Mendel**.
