d) Submarine

INS Sindhukesari is a Sindhughosh-class diesel-electric submarine belonging to the Indian Navy. This 3,000 tonne submarine underwent a major ‘medium refit-cum-life extension’ in Russia’s Severodvinsk that ended in 2018.
INS Sindhukesari recently reached Jakarta in Indonesia for the ‘maiden operational turnaround’ via the Sunda Strait. This is the first long-range deployment of a submarine.

d) 1 only

A Neutrino is a fermion (an elementary particle with spin of 1 / 2 ) that interacts only via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small (-ino) that it was long thought to be zero. Hence, statement 1 is correct.

Neutrinos are the second most abundant particles in the cosmos, produced in copious amounts in the cores of stars. Neutrinos are the second-most abundant particle in the universe after light particles (photons). Hence, statement 2 is incorrect.

For each neutrino, there also exists a corresponding antiparticle, called an antineutrino, which also has spin of 1 / 2 and no electric charge. Antineutrinos are distinguished from neutrinos by having opposite-signed lepton number and weak isospin, and right-handed instead of left-handed chirality. Hence, statement 3 is incorrect.

The Kamioka Liquid Scintillator Antineutrino Detector (KamLAND) experiment in Japan has found no evidence that neutrinos are their own antiparticles.

The US administration has unveiled a new Commercial Arms Transfer (CAT) policy that places greater emphasis on human rights in its arms export policy,
This is in contrast to the Trump-era policy that gave more importance to commercial considerations. The new policy covers the review of government-to-government weapons transfers, security assistance, and licensed commercial sales of US-origin military equipment overseen by various government departments.
