Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of chemical reaction in which a substance gains electron?
A
Reduction
B
Oxidation
C
Decarboxylation
D
Dehydrogenation
Explanation: 

Detailed explanation-1: -Complete answer: In oxidation/reduction reactions, there is a transfer of charge-an electron-from one species to another. Oxidation is the loss of electrons and reduction is a gain in electrons.

Detailed explanation-2: -The loss of electrons is called oxidation. The gain of electrons is called reduction.

Detailed explanation-3: -What is Reduction Reaction? Like oxidation reactions, reduction reactions are defined as the gain of electrons. Any substance that gains electrons during a chemical reaction gets reduced.

Detailed explanation-4: -The oxidizing agent gains electrons and is reduced in a reaction that takes at an electrode is called the cathode.

Detailed explanation-5: -Reduction is the gain of electrons, loss of oxygen or gain of hydrogen.
