Answer:
C.) to demonstrate how cowardly the British army can be
Explanation:
The "American Crisis" which is a series of articles were written by Thomas Paine between 1776 to 1783. One of the purposes of the article is to inspire the Americans to fight the British in their quest for the Revolution War.
He, however, referred to Joan of Arc, by stating that "...Britain has trembled like an ague at the report of a French fleet of flat-bottomed boats; and... after ravaging the kingdom of France, was driven back like men petrified with fear; and this brave exploit was performed by a few broken forces collected and headed by a woman, Joan of Arc."
Hence, it can be concluded that Paine most likely refers to Joan of Arc "to demonstrate how cowardly the British army can be."
