Answer: Option (a) is the correct answer.

Step-by-step explanation:

A chemical reaction is the reaction that involves gain and loss of electrons due to which there is formation of new compounds or products.

Foe example,
$HCl + NaOH \rightarrow NaCl + H_(2)O$

That is, in chemical reactions change in oxidation state of reactants occur.

Hence, we can conclude that out of the given options electrons participates in chemical reactions.

I think the correct answer is electrons. All chemical reactions are dependent on the transfer of electrons. Other subatomic particles are located in the innermost portion of an atom and are bonded strongly with each other.
