The correct answer is A. Gene mutation.
Gamma rays are a type of high-energy radiation that can cause damage to DNA, the genetic material in cells. This damage can lead to mutations, which are changes in the DNA sequence. Mutations can be harmful or beneficial, and they can be passed down to future generations.
Sneezing is a reflex that helps to clear the nose of irritants. It is not caused by gamma rays.
Burning is a type of injury that is caused by heat or radiation. It can be caused by gamma rays, but it is not the most common effect.
Fever is a rise in body temperature that is often caused by an infection. It is not caused by gamma rays.
In addition to gene mutation, gamma rays can also cause other health problems, such as cancer, cataracts, and skin burns. They can also cause reproductive problems, such as infertility and birth defects.
If you are exposed to gamma rays, it is important to seek medical attention immediately. There is no cure for radiation poisoning, but there are treatments that can help to reduce the severity of the symptoms.
