reduction 

"Reduction refers to ( chemical reactions in which a molecule gains electrons.)"

Answer:

The correct answer would be c.)reduction

Oxidation and reduction occur when transfer of electrons takes place from one element or atom to another.

The atom which receives or gains electron is said to be reduced while the atom which looses an electron is said to be oxidized.

For example, in cellular respiration oxygen gains electrons and H⁺ ions and is converted into water which is released as the byproduct of the process.

1/2 O₂ + 2 e⁻ + 2 H⁺ → 2H₂O
