I think it's B.

Is anybody (singular - one person) "THEY"? You're on your own now.

The sentence that correctly uses pronouns is A. "If people want to succeed in life, they must know the rules of the game."

The pronoun "they" is used correctly as a gender-neutral pronoun to refer to the plural noun "people". It is important to use pronouns that agree in number and gender with the nouns they refer to. In this case, "they" agrees with "people".
