(a) Richard Feynman
(b) Murray Gell-Mann
(c) Albert Einstein
(d) Neils Bohr

Answer: (b) Murray Gell-Mann
A quark is an elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei.

The quark model was independently proposed by physicists Murray Gell-Mann and George Zweig in 1964. Quarks were introduced as parts of an ordering scheme for hadrons, and there was little evidence for their physical existence until deep inelastic scattering experiments at the Stanford Linear Accelerator Center in 1968. Accelerator experiments have provided evidence for all six flavours. The top quark was the last to be discovered at Fermilab in 1995.
