52. India-based Neutrino Observatory is included by the Planning Commission as a mega science project under the 11th Five-Year Plan. In this context, consider the following statements
1. Neutrinos are charge less elementary particles that travel close to the speed of light.
2. Neutrinos are created, in nuclear reactions of beta decay.
3. Neutrinos have a negligible, but non-zero mass
4. Trillions of Neutrinos pass through human body every second.
Which of the statements given above are correct?

Which of the statements given above are correct?
The correct option is D (d) 1, 2, 3 and 4
(D)
A neutrino is an elementary particle that usually travels close to the speed of light, is electrically neutral, and is able to pass through ordinary matter almost undisturbed. This makes neutrinos extremely difficult to detect. Neutrinos have a very small, but nonzero rest mass. Neutrinos are affected only by a ‘weak’ sub-atomic force of much shorter range than electromagnetism, and are therefore able to pass through great distances in matter without being
affected by it.
