Final answer:
King James II's monarchy faced concerns regarding his conversion to Catholicism, centralization of power, and maintenance of a standing army.
Step-by-step explanation:
During King James II's monarchy, there were three main problems that people in England and its colonies maintained concerns about. The first problem was James' conversion to Catholicism and his appointment of Catholics to positions of power. This raised fears of a Catholic monarchy and the potential suppression of religious freedom. The second problem was James' centralization of political power, which threatened the freedom and rights of the English people. Lastly, the maintenance of a standing army in times of peace and the belief that it would be used to crush liberty was another concern.
