Which of the following is NOT true about baryons?

Baryons are a category of subatomic particles that are fundamentally important in the study of particle physics. One key characteristic of baryons is that they are composed of three quarks. This is a primary defining feature, distinguishing them from other hadrons like mesons, which are made up of one quark and one antiquark.

Baryons include well-known particles such as protons and neutrons, which indeed account for a significant portion of atomic mass and are essential components of atomic nuclei. They are assigned a baryon number of +1, reinforcing their classification within the family of baryons.

Given that baryons consist of three quarks, the statement claiming that baryons are made of two quarks is incorrect, thus identifying that specific statement as not true regarding baryons.
