The correct option is A
A constitutional convention is a political meeting, which aims to draft a new constitution or revise an existing one. In the United States of America, all states have the right to hold constitutional conventions, whether limited or general. Usually, they are proposed by one of the chambers of the Legislative Power of the state, and must be approved by the majority (51%, 60% or 67%, depending on the state) of the members of both legislative chambers and then by the majority of the population of the state (51%). Several American states allow the population, through manifestos (with a minimum number of signatures, generally between 5% and 10% of the electoral population), to propose constitutional conventions, which will need to be ratified by the majority of the members of both Legislative cameras, in addition to the population of the state.
