Leptons are a category of particles that include electrons, muons, tau particles, and their corresponding neutrinos. These particles are characterized by having a spin of 1/2, which is a fundamental property of all fermions. Baryons and mesons, on the other hand, can have different spin values. Baryons (like protons and neutrons) are also fermions with spin 1/2, but the question specifically asks for the group that exclusively contains particles with spin 1/2, making leptons the correct answer. Mesons are bosons and can have integer spin values, not exclusively 1/2.
