Hint: From the given question we can take hints that the question is talking about an ion which has some charge on it.

Step by step solution:
This question is talking about ions. And an ion is a charged atom or molecule. It is charged because the number of electrons do not equal to the number of protons in the atom or molecule. For example: \[N{{a}^{+}}\], \[{{O}^{2-}}\]etc.

And we know that there are two types of ions:

Cations: A positively charged ion is known as cation. And a cation is formed by the loss of one or more electrons by an atom or molecule. For example: Sodium atom loses one electron to form a positively charged sodium ion, \[N{{a}^{+}}\], which is cation. One more thing is that all the metals are cations. Cations are attracted by cathode in electrolysis.

Anions: Anion is a negatively charged ion. An anion is formed by the gain of one or more electrons by an atom. For example a chlorine atom gains 1 electron to form chloride ion, \[C{{l}^{-}}\], which is an anion. An anion contains more electrons than a normal atom. The ions of all non metal elements are anions. Anions are attracted to the anode.

Positron is a subatomic particle with the same mass as an electron and a numerically equal but positive charge. And protons and positrons are two different things. Positron is a very stable particle where positron is a very unstable particle.

From the above points we can conclude that the correct answer is “A”, all others are incorrect.

Note: This question is totally memory based. You have to remember which type of charged particle known by what name. These names are based on their Greek words.
