Answer:
Option B. Parish priests generally came from the peasantry, bishops and other highly placed clergy came from the nobility.
Step-by-step explanation:
A parish priest is a priest appointed by a bishop to represent him in a local parish, which is a collection of neighborhoods in one small region of a county within a given state.
In the middle ages, the clergy had a subdivision in the main hierarchy. At the top resided the priests and bishops, who came from noble families, were more powerful, and wealthier and more educated than their counterparts: The parish priests, who resided at the bottom.
As pointed by the definition, a parish priest would not entitle himself with the position, but would rather only be appointed by a member of the high clergy. This person would normally come from a family of commoners and be illiterate as well.
