Answer: Option (B) is the correct answer.
Step-by-step explanation:
When an atom gains electrons then it becomes rich in electrons and therefore it acquires a negative charge.
Also, it is known that a reduction reaction is a reaction in which an element gain electron(s).
For example,
is a reduction reaction.
Thus, we can conclude that when nonmetal atoms become negative nonmetal ions then type of reaction which occurs is reduction reaction.
