The correct answer for the kind of majority required for constitutional amendment in forming a new state is option 1, simple majority. This means that more than 50% of the votes are required in favor of the amendment in order for it to be approved. Option 2, two-thirds majority, and option 3, three-fourths majority, are incorrect because they require a higher percentage of votes than a simple majority. Option 4, two-thirds majority plus ratification by half of all states, is also incorrect as it includes an additional requirement of ratification by half of all states, which is not necessary for a constitutional amendment in forming a new state. It`s important to note that the specific requirements for constitutional amendments can vary depending on the country or jurisdiction in question.
