According to quantum chromodynamics, the force that keeps quarks confined within a proton or neutron) increases as the separation between the individual quarks increases. Which statement below best represents this scenario? A) The quarks are tied together by nonstretchable strings. B) The quarks are tied together by elastic strings. C) The quarks move independently of each other. D) The force between the quarks has a 1/r² behavior like gravity. E) The potential energy of a quark decreases with separation.

According to quantum chromodynamics, the force between quarks increases as they are separated, similar to how an elastic string resists stretching as it is pulled apart. Therefore, choice B, which suggests that the quarks are tied together by elastic strings, is the best representation of this scenario.
