Final answer:
The body of Catholic clergymen that met from 1545 to 1563 to consider the reform of the church is known as the Council of Trent. They addressed church abuses and doctrinal reaffirmations, notably prohibiting the sale of indulgences and insisting on clerical training without amending core Catholic doctrines.
Step-by-step explanation:
The council you are referring to is the Council of Trent, which spanned from 1545 to 1563. This assembly of high-ranking Catholic officials met over 25 sessions, predominantly in the town of Trent, to address issues arising from the Protestant Reformation and to reform the Catholic Church. The Council of Trent initiated several important reforms, including the prohibition of selling indulgences, the introduction of better training for clergy, and the establishment of the Doctrine of Merit.
It also reaffirmed critical aspects of Catholic doctrine, such as the importance of the seven sacraments, the existence of Purgatory, and the authority of scripture coupled with the Church's teachings and traditions. The correct answer to the question is B) Council of Trent.
