In summary, C is the right answer! "Recapitulate" is ultimately derived from the Latin prefix "re-," meaning "again," and "capitulum," meaning "chapter." "Capitulum" itself comes from the Latin word "caput," meaning "head," and was used in the Middle Ages for the divisions in a book, usually marked with a different heading for each chapter. "Capitulum" has given English "recapitulate," "capitulate" (meaning "to negotiate" or "to agree to"), and, naturally, "chapter."
