Answer:
B. Receiving money for the remission of sins
Explanation:
There were several excesses and corrupt practices that pervaded the the Roman Catholic Church, of which Margin Luther, in his "95 Theses" criticized.
The papal practice which request and encourages people, even the poorest, to pay for the remissions of their sins by buying what was called "indulgences", was the act of the Catholic Church that Luther strongly condemned the most in his theses.
Luther further reinstates that deeds and works of Christians cannot earn them salvation, saved by faith alone, and that the Bible is the final source of authority on any matter, as long as Christianity is concerned.
