The 1912 constitutional convention resulted in a series of amendments being proposed, not a new constitution being written and adopted like option B suggests. Option C is also incorrect because significant changes were made at the convention. Option D is incorrect because a single-party system was not introduced at the 1912 convention. Instead, it resulted in a multi-party system with party primaries being implemented. This ultimately led to the formation of the two-party system in American politics. Therefore, the correct answer is A, as it accurately reflects the outcome of the 1912 constitutional convention.
