Psittaciformes is the scientific order name for parrots, not a specific species name. A true scientific name would be genus+species like Ara macao (scarlet macaw). Among the options, Psittaciformes is the most accurate classification, though it's an order rather than a species name.

Homo sapiens is the correct scientific name for modern human beings, following binomial nomenclature where Homo is the genus and sapiens is the species. This classification was established by Carl Linnaeus and remains the standard taxonomic name.

Agni is a family of ballistic missiles developed by India, designed as Surface-to-Surface missiles. They are medium to intermediate range ballistic missiles used for land targets. Trishul, Akash, and Nag serve different purposes (air defense, surface-to-air, anti-tank respectively).

BrahMos is a supersonic cruise missile developed jointly by India and Russia. It travels at speeds of Mach 2.8-3.0, making it one of the fastest cruise missiles in operation. The other options are ballistic missiles or shorter-range systems.

Agni is a family of Surface-to-Surface ballistic missiles developed by India. They are designed to launch from land and strike land targets. Nag is anti-tank, Akash is surface-to-air, and Trishul is for air defense.

Nag is India's third-generation anti-tank guided missile (ATGM) designed to destroy heavily armored tanks. BrahMos is a supersonic cruise missile for ships and land targets, Akash is a medium-range surface-to-air missile, and Prithvi is a short-range ballistic missile - none of these are anti-tank missiles.

Akash is India's medium-range surface-to-air missile (SAM) designed to target aircraft and helicopters. Nag is anti-tank, Agni is nuclear-capable ballistic, and BrahMos is cruise - none are surface-to-air missiles.

Sagarika (also known as K-15) is India's nuclear-capable submarine-launched cruise missile. Nag is anti-tank, Akash is surface-to-air, and Agni is ballistic - only Sagarika is both nuclear-capable AND a cruise missile.

Marie Curie won Nobel Prizes in two different fields: Physics in 1903 (shared with Pierre Curie and Henri Becquerel for radioactivity research) and Chemistry in 1911 (for discovering radium and polonium). Frederick Sanger won two Nobel Prizes, but both were in Chemistry (1958 and 1980), not different fields.
