根据材料，回答题。 The first navigational lights in the New World were probably lanterns hung at harbor en-trances. The first lighthouse was put up by the Massachusetts Bay Colony in 1716 on Little Brewster Island at the entrance to Boston Harbor. Paid for and maintained by "light dues" levied （征收） on ships， the original bcacon was blown up in 1776. Until then there were only a dozen or so true lighthouses in the colonies. Little over a century later， there were 700 lighthouses. The first eight lighthouses erected on the West Coast in the 1850s featured the same basiC．New Eng.and design:a Cape Cod dwelling with the tower rising from the center or standing close by. In New England and elsewhere， though， lighthouses reflected a variety of architectural styles. Since most stations in the Northeast were set up on rocky eminences （高出）， enormous towers were not the rule. Some were made of stone and brick， others of wood or metal. Some stood on pilings or stilts; some were fastened to rock with iron rods. Farther south， from Maryland through the Florida Keys， the coast was low and sandy. It was often necessary to build tall towers there——massive structures like the majestiC．lighthouse in Cape Hatteras， North Carolina， which was lit in 1870. 190 feet high， it is the tallest brick lighthouse in the country. Not withstanding differences in construction appearance， most lighthouses in America shared several features : a light， living quarters， and sometimes a bell （or， later， a foghorn）. They also had something else in common: a keeper and usually the keeper"s family. The keeper"s essential task was trimming the lantern wick （灯芯） in order to maintain a steady， bright flame. The earliest keepers came from every walk of life， they were seamen， farmers， mechanics， rough mill hands and appointments were often handed out by local customs commissioners as political plums. After the administration of lighthouse was taken over in 1852 by the United States Lighthouse Board， and agencv of the Treasury Department， the keeper corps gradually became highly profes-sional. Which is the best title for the passage？ 查看材料 A.The Lighthouse on Little Brewster Island. B.The Life of a Lighthouse Keeper. C.Early Lighthouses in the United States. D.The Modern Profession of Lighthouse-keeping. 请帮忙给出正确答案和分析，谢谢！
