The correct answer is B. Charged particles emitted by nucleus.
Beta rays are a type of ionizing radiation that is emitted by radioactive materials. They are high-energy electrons or positrons that are ejected from the nucleus of an atom during radioactive decay. Beta rays can travel through air and other materials, and they can cause damage to living cells.
Option A is incorrect because electrons orbiting around the nucleus are not beta rays. Electrons in an atom are held in orbit around the nucleus by the electromagnetic force. They are not ejected from the nucleus during radioactive decay.
Option C is incorrect because neutral particles are not beta rays. Beta rays are charged particles, either electrons or positrons.
Option D is incorrect because beta rays are not electromagnetic radiation. Electromagnetic radiation is a type of energy that is emitted by atoms and molecules. It includes visible light, radio waves, and microwaves. Beta rays are not electromagnetic radiation because they are charged particles.
