India-based Neutrino Observatory (INO), 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 chargeless 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 nonzero mass.
$4$. Trillions of neutrinos pass through the human body every second.
Which of the statements given above are correct?

A team of scientists at Brookhaven National Laboratory, including those from India, created the heaviest antimatter (anti-helium nucleus). What is/are the implication/implications of the creation of antimatter? 

1. It will make mineral prospecting and oil exploration easier and cheaper.
2. It will help probe the possibility of the existence of stars and galaxies made of antimatter.
3. It will help us understand the evolution of the universe.

Select the correct answer using the codes given below:

The efforts to detect the existence of Higgs Boson particles have become frequent news in the recent past. What is/is the importance/importance of discovering this particle?
1. It will enable us to understand why elementary particles have mass.
2. It will enable us in the near future to develop the technology of transferring matter from one point to another without traversing the physical space between them.
3. It will enable us to create better fuels for nuclear fission.
