What mechanisms were introduced to amend the Ohio Constitution of 1851?

In 1851, Ohio implemented a new state constitution that included three mechanisms for making amendments constitutional convention, initiative, and general assembly. The other options are incorrect because they only list a single mechanism, whereas the correct answer lists all three. Constitutional convention refers to a convention called by the legislature to make amendments, initiative refers to a process by which citizens can propose amendments, and general assembly refers to the state's legislative body. These multiple options demonstrate the state's commitment to a democratic process and the flexibility for amendments to be made through various methods.
