Solution
The radiations that are not human friendly are Gamma rays and x-rays (Option A). These types of radiation are known as ionizing radiation and they have enough energy to remove tightly bound electrons from atoms, thus damaging our cells and DNA. Prolonged exposure to these radiations can lead to health problems like cancer and radiation sickness.
