Mutations can be induced with:

Options

A. Gamma radiations
B. Infrared radiations
C. IAA
D. Ethylene

Answer

**Step-by-Step Solution:**

1. **Understanding Mutations**: Mutations are changes in the DNA sequence of an organism. They can occur naturally or can be induced by various external factors.

2. **Types of Mutations**: There are different types of mutations, including point mutations, which involve a change in a single nucleotide in the DNA sequence.

3. **Inducing Mutations**: Certain types of radiation and chemicals can induce mutations. The question specifically asks for methods to induce mutations.

4. **Analyzing the Options**:
- **Gamma Radiation**: This is a type of high-energy radiation that can cause mutations by damaging the DNA.
- **Infrared Radiation**: This type of radiation is generally not strong enough to cause mutations in DNA.
- **IAA (Indole-3-acetic acid)**: This is a plant hormone and does not induce mutations.
- **Ethylene**: This is a plant hormone involved in growth and development, not in inducing mutations.

5. **Conclusion**: Among the given options, gamma radiation is the only one that can effectively induce mutations.

**Final Answer**: Mutations can be induced with gamma radiation.
