Answer:
B and A are the correct answers.
Explanation:
The word tithe is very important in both questions, and it works in the same way. In the first one, letter B is correct since at a point in Church's history, it was not optional to pay the tithe, which is the tenth part of a person's earnings. Due to this, it means that he has no choice in his career.
In part B, A is correct, based on the same definition of not being optional, meaning that the tithe was mandatory, giving the object a sense of obligation.
