Option C. The "Pagans" described in the last lines of the excerpt above are the European colonists.
Step-by-step explanation:
"A Key Into the Language of America" is a book written by Roger Williams in 1643 that describes the American Indian Languages found in New England during the 17th century, mainly Narragansett, an Algonquian language.
