Which of the following best describes why Candide’s mother would not marry his father?

B. His father is unable to prove enough nobility in his family.

The old servants of the family suspected him to have been the son of the Baron's sister, by a good, honest gentleman of the neighborhood, whom that young lady would never marry because he had been able to prove only seventy-one quarterings, the rest of his genealogical tree having been lost through the injuries of time.
