Option B.
Step-by-step explanation:

A popular referendum is a kind of a referendum that presents a method through which a petition approved by a specified minimum number of enrolled voters can require a public referendum on an existing law, constitutional or charter amendment or, in its least application, to simply require the legislative or executive divisions to reflect the subject by presenting it to the status of the day.
