A. Because
B. Thanks to
C. Thanks for
D. With the help of
答案：
A. Because
(答案→)B. Thanks to
C. Thanks for
D. With the help of
解析：because是连词，连接句子，本句不需要连词；with the help of是“在…的帮助之下”，本句用它不符合逻辑。thanks to means 幸亏，由于。thanks formeans 感谢某人做了某事例，如：Thanks to the car, I was able to get back home in time.幸亏有汽车代步，我才得以及时赶回家。故选B。
