Which fundamental particle is a sub-part of proton
Answer is Quarks (Option A)
Quarks are the fundamental particles that make up a proton. A proton is composed of two up quarks and one down quark, which are held together by the strong nuclear force mediated by gluons (which are also considered fundamental particles). Quarks are fermions, which are a class of particles that obey Fermi-Dirac statistics and have half-integer spin.
