Baryons and mesons are types of particles that consist of quarks.
Which row of the table shows a possible quark composition for a baryon and for a meson?
The only correct answer is D
A is not correct as The first composition would be a meson, not a baryon, and the second
composition has too many quarks for a meson.
B is not correct as The first composition is possible for a baryon, but the second composition
has 2 quarks rather than a quark and an antiquark.
C is not correct as This shows a possible meson in the baryon column and vice versa
