The correct Answer is:
### Step-by-Step Solution: 1. **Understanding X-ray Exposure**: X-rays are a form of ionizing radiation that can penetrate biological tissues. When cells are exposed to X-rays, they can cause damage to the DNA within those cells. 2. **Effect of X-rays on Chromosomes**: The exposure to X-rays can lead to mutations in the genetic material. This is because X-rays can break the DNA strands or cause other types of damage that may alter the structure and function of chromosomes. 3. **Increased Frequency of Mutations**: As a result of the DNA damage caused by X-rays, the frequency of mutations in the genetic material increases. Mutations can lead to changes in the traits of an organism. 4. **Link to Crossing Over**: The increased mutations and changes in chromosome stability can enhance the process of crossing over during meiosis. Crossing over is the exchange of genetic material between homologous chromosomes, which increases genetic diversity. 5. **Conclusion**: Therefore, the exposure of X-rays enhances the frequency of crossing over due to the mutations and changes in the stability of chromosomes that result from the exposure.
