FYI:
•The tribes of Nagaland celebrate the festival with gusto and fervour while more than 60 percent of the Nagaland’s population depends on agriculture and therefore most of their festivals revolve around agriculture.
•Nagaland is known as land of festivals and to encourage inter-tribal interaction and to promote cultural heritage of Nagaland, the Government of Nagaland organises the Hornbill festival every year. It is also known as the festival of festivals.
•The festival was held from December 1 to 10 at Naga Heritage Village, Kisama, around 12 km from the state capital Kohima. It promotes the rich and colourful culture of Nagaland and its tribes.
•Therefore, option (c) is the correct answer.

(d)
FYI:
•The Doctrine of Basic Structure is a form of judicial review that is used to test the legality of any legislation by the courts. It was evolved by the Supreme Court in the 1973 landmark ruling in Kesavananda Bharati v State of Kerala.
•In a 7-6 verdict, a 13-judge Constitution Bench ruled that the ‘basic structure’ of the Constitution is inviolable, and could not be amended by Parliament.
•If a law is found to “damage or destroy” the “basic features of the Constitution”, the Court declares it unconstitutional. The test is applied to constitutional amendments to ensure the amendment does not dilute the fundamentals of the Constitutional itself.
•The court ruled that while Parliament has vast powers to change the Constitution, it cannot touch certain “basic features” or foundational principles that give the Constitution its coherence or identity. The Parliament can amend the basic structure but cannot destroy it.
•Therefore, option (d) is the correct answer.

FYI:
•Crypto jacking is a cyber-attack wherein a computing device is hijacked and controlled by the attacker, and its resources are used to illicitly mine cryptocurrency.
•Coin mining is a legitimate, competitive process used to release new crypto coins into circulation or to verify new transactions.
•It involves solving complex computational problems to generate blocks of verified transactions that get added to the blockchain.
•Therefore, option (c) is the correct answer.

(a)
FYI:
•CSIR-NEERI developed new formulations for reduced emission light and sound emitting crackers (SWAS, SAFAL, STAR) with 30% reduction in particulate matter using Potassium Nitrate (KNO3) as oxidant.
•SWAS is a safe water releaser, which suppresses the dust released by releasing water vapour in the air. It does not comprise potassium nitrate and sulphur while the particulate dust released will be reduced approximately by 30 per cent.
•STAR is the safe thermite cracker, which does not comprise potassium nitrate and sulphur, emits reduced particulate matter disposal and reduced sound intensity.
•SAFAL is safe minimal aluminium which has minimum usage of aluminium and used magnesium instead. It ensures reduction in sound in comparison to traditional crackers.
•Therefore, option (a) is the correct answer.

FYI:
— Kanthalloor is a rain-shadow village on the Eastern slopes of the Western Ghats, lying nearly 40 km away from Munnar, Kerala.
