B.    Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast), which不指代前句 gave consumers relatively inexpensive houses and furniture, but also
C.    The systematic clearing of forests in the United States, creating farmland (especially in the Northeast) and giving consumers relatively inexpensive houses and furniture, but also
D.    The systematic clearing of forests in the United States created farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also
