The reactants that are used in the reaction are Sodium metal and water. The correct option is C.
A chemical reaction is the chemical transformation of one set of chemical substances into another.
When chemical bonds between molecules are established or broken, chemical reactions occur.
The substances that initiate a chemical reaction are known as reactants, and the substances that result from the reaction are known as products.
Living things (cells, animals, humans, and insects) use chemical reactions to grow, develop, reproduce, and adapt.
In the given reaction, sodium and water are reacting with each other forming sodium hydroxide and hydrogen gas along with heat and light.
So, here the reactants are sodium metal and water, while products are sodium hydroxide and hydrogen gas.
Thus, the correct option is C.
