单选题 The period in Europe from the end of the World War II has seen a spectacular growth in the number of cars, similar to ______ in America during the 1920s and 1930s.
A. what would take place B. that which took place
C. which had taken place D. that were taking place

【正确答案】 B

【答案解析】[解析] 本题中“similar to”后面的部分是与前面的“growth in the number of cars”相比较，因此应用指示代词“that”；“that”后面是定语从句，应用关系代词which引导。因此B项正确。
