With reference to neutrino, consider the following statements: Neutrin...
Proton, neutron, and electron are tiny particles that makeup atoms. The neutrino is also a tiny elementary particle, but it is not part of the atom. Such particles are also found to exist in nature. Hence statement 1 is correct.
Neutrino has a very tiny mass and no charge. It interacts very weakly with other matter particles. So weakly that every second trillion of neutrinos fall on us and pass through our bodies unnoticed. Neutrinos come from the sun (solar neutrinos) and other stars, cosmic rays that come from beyond the solar system, and from the Big Bang from which our Universe originated. They can also be produced in the lab. Hence statement 3 is correct.

They can also be produced in the lab. Hence statement 3 is correct.
The INO (India based Neutrino Observatory) will study atmospheric neutrinos only. Solar neutrinos have much lower energy than the detector can detect. INO Project is aimed at building a world-class underground laboratory with a rock cover to conduct basic research on the neutrino. The Tata Institute of Fundamental Research is the nodal institution. The observatory is to be built jointly with the Department of Atomic Energy and the Department of Science and Technology. The observatory will be located underground so as to provide adequate shielding to the neutrino detector from cosmic background radiation.
The operation of INO will have no release of radioactive or toxic substances. It is not a weapons laboratory and will have no strategic or defence applications.
They are the second most abundant particle in the universe after particles of light called photons. Hence statement 2 is not correct.

With reference to neutrino, consider the following statements: Neutrin...
Neutrino Properties:
- Neutrino is a tiny elementary particle with no charge: This statement is correct. Neutrinos are extremely small particles that have no electric charge, making them very difficult to detect as they do not interact with electromagnetic forces.
Neutrino Abundance:
- Neutrinos are the most abundant particles in the universe: This statement is incorrect. While neutrinos are indeed abundant in the universe, they are not the most abundant particles. Photons, which make up light, are the most abundant particles in the universe.
Neutrino Production:
- Neutrinos can be produced in the laboratory even though they are naturally occurring: This statement is correct. Neutrinos can be produced in laboratory settings through processes such as nuclear reactions or particle collisions. While neutrinos are naturally occurring, scientists can also create them in controlled environments for research purposes.
Therefore, the correct statements are 1 and 3 only, making option 'B' the correct answer.
