D Correct answer
Explanation

Mesons are subatomic particles composed of one quark and one antiquark, bound together by the strong interaction. Because mesons are composed of sub-particles, they have a physical size, with a radius roughly one femtometer: 10-15 m, which is about 2⁄3 the size of a proton or neutron.
