Answer:
A) Used her pregnancy as a defense.
Step-by-step explanation:
Daniel Defoe's "Moll Flanders" tells the story of the protagonist Moll Flanders who was born to a criminal mother. But she grew into a beautiful woman and taking advantage of her situation, she also became notorious for her crimes.
The given passage is from when Moll begins her narration about how she was born. Her "mother was convicted of felony for a certain petty theft scarce worth naming, viz. having an opportunity of borrowing three pieces of fine holland of a certain draper in Cheapside". She used her pregnancy as an excuse to be exempted from being put in captivity, thus, giving her daughter the benefit of being born out of prison. The phrase "pleaded her belly" means she used her pregnancy as an excuse/ defense from being convicted or put to punishment.
