Answer:
The correct answer is b) Luther's following of academic custom in publishing his Ninety-Five Theses.
Step-by-step explanation:
John Tetzel was a man hired to raise money for the construction of St. Peter's Basilica that would be built in Rome, he was considered very good in the field of sales. But, to collect the money from the Basilica, he used the sale of indulgences.
Indulgences were a merit that the Catholic Church had, it granted forgiveness of the sins of the people that the church chose.
John Tetzel sold the idea to people that if they paid for the indulgence their dead relative would stop being in purgatory and go to heaven.
These actions provoked the protests of Martin Luther, who considered abuse by the church the commercialization of indulgences. He considered that forgiveness was the internal repentance of the person, which was not related to the indulgences that the church gave.
Martin Luther protested writing a document known as the ninety-five theses, a thesis that went against some Catholic traditions, giving way to the Protestant Reform.
