Which fundamental force of nature is responsible for holding the quarks together inside protons and neutrons?

💡 Solution & Explanation

The strong nuclear force is the fundamental interaction mediated by gluons that binds quarks together to form composite hadrons like protons and neutrons. Other options such as the electromagnetic force govern charged particle interactions, and gravity operates on mass at macroscopic scales. This fundamental force is notable for being the strongest of all four interactions at subatomic distances.
