The correct answer is B. People should vote on Election Day because it is the most direct way to express their opinions.
Explanation:
In grammar, a broad pronoun reference is the use of a pronoun including the words this, that, which or it, to refer to a broad idea or clause, this means in a broad pronoun reference these words do not replace nouns as usual but replace complete sentences or clauses. This type of construction should be used only if the relation between the antecedent or complete clause the pronoun is referring to is strong and evident, otherwise, it would only create a confusing grammatical construction. Considering this from the options the choice that contains a broad pronoun reference is "People should vote on Election Day because it is the most direct way to express their opinions", because in this option the pronoun "it" refers to the complete sentence "People should vote on Election Day", which means a pronoun has been used to refer or replace a complete sentence instead of a noun which is what a broad pronoun reference is about.
