单选题 He didn't notice me in the erowd; but he spotted my sister who was ______ because of her red hair.
A. conscious B. conspicuous C. dim D. conscientious

【正确答案】 B

【答案解析】[解析] B项“conspicuous显著的”符合题意。如：He was conspicuous for his bravery．(他因骁勇而出名。)其他三项“A项conscious有意识的；C项dim暗淡的，模糊的；D项conscientious尽责的”都不正确。本题是说他没在人群中发现我，但发现了我姐姐，因为她的红发非常惹人注目。因此B项为正确答案。
