Correct Answer: Physics

Solution : The correct option is Physics .

Astrophysics and, more precisely, the discovery of high-energy neutrinos are linked to the Askaryan effect. The phenomenon known as the Askaryan effect occurs when a high-energy neutrino interacts with materials to produce secondary charged particles, which in turn causes the emission of an electromagnetic pulse. It is in a dense medium, like salt or ice, that this interaction takes place. The effect was initially described in 1962 by the Soviet-Armenian physicist Gurgen Askaryan. In tests with quantities of transparent medium, like Antarctic ice, the Askaryan effect is used to find high-energy neutrino presence.
