O. By using the power of lay investiture.

Explanation:

Lay Investiture is the system or process when the religious leaders are elected and given appointment by the rulers or monarchs of secular states or kingdoms. This allows the monarchs to have control over the religious aspect of authority instead of the papal authority appointing the smaller church leaders.

Otto I was the ruler of Germany and the Roman empire after the death of his father Henry I. He took upon himself to install the leadership of the local church. Though this was supposed to be the rights and duty of the church in appointing these local leaders, Otto's act of appointing these local leaders led to an increase in his loyal followers. This practice of investiture gained a large number of support from the Church bishops, furthering his power and leadership.

the first 10 amendments to the u.s. constitution are known as the bill of rights. those 10 amendments establish the most basic freedoms for americans including the rights to worship how they want, speak how they want, and assembly and peaceably protest their government how they want. the amendments have also been subject to much interpretation since their adoption, particularly the right to carry a gun under the second amendment.

"a bill of rights is what the people are entitled to against every government on earth, general or particular, and what no just government should refuse, or rest on inference," said thomas jefferson, the author of the declaration of independence and the third president of the united states.
