Mark all the baryonsa) Proton b) Electron c) Anti-top d) Gluon e) Tau Neutrino

The correct options are:

1) Protons

Explanation:

Brayons are composite subatomic particles which consist of odd number of valence quarks. Quarks are the fundamental particles in the nature that combine to form other particles such as neutrons and protons. In these composite subatomic particles strong nuclear forces dominate as compared to other fundamental forces in the nature.

A list of brayons includes (names are as represented in theory):

1) Proton's

2) Neutrons

3) Lambda

4) Sigma

5) Xi

6) Omega

7) Delta

Hence we find only proton is matching from the given options.
