Which of the following best describes an electric charge?

-Positive or negative terminal of a battery
-property of electrons, protons, and neutrons
-materials that conducts current
-has a north pole and a south pole

The best description of an electric charge is that it is a property of electrons, protons, and neutrons. In order to understand this, we need to have some basic knowledge about atoms.

Atoms are the building blocks of matter. They consist of a nucleus, which contains positively charged protons and uncharged neutrons, and negatively charged electrons which orbit the nucleus.

Electric charge is a fundamental property of particles, specifically electrons and protons. Electrons are negatively charged, while protons are positively charged. Neutrons, on the other hand, have no electric charge and are neutral.

It is important to note that electric charge is not limited to electrons, protons, and neutrons. It can also exist in other forms, such as ions or charged particles formed when atoms gain or lose electrons.

So, the best description of an electric charge would be that it is a property of electrons, protons, and neutrons.
