Solution

The nucleus of Beryllium (Be) contains 9 protons and 5 neutrons.

  1. Hadrons: These are particles made of quarks. Both protons and neutrons are hadrons. So, the total number of hadrons in a Be nucleus is 9 (protons) + 5 (neutrons) = 14.

  2. Baryons: These are hadrons made of three quarks. Both protons and neutrons are baryons. So, the total number of baryons in a Be nucleus is also 14.

  3. Mesons: These are hadrons made of a quark and an antiquark. There are no mesons in a nucleus under normal conditions. So, the number of mesons in a Be nucleus is 0.

So, the correct answer is not listed in the options provided. The correct counts would be 14 hadrons, 14 baryons, and 0 mesons.
