[单项选择]Bob and Annie had not known each other long before they became eager to get married: Bob because he wanted Annie and she ( though she was fond of Bob in her own way) because she could at least lead a life away from her family. When Mrs. Thompson suggested that they marry and live with her in Dover Street until they could get a house of their own, Annie hesitated. Her idea of marriage had been something which brought her a husband and an orderly, well-furnished home all at once. But she soon saw the advantages of this arrangement. She would, first of all, escape from her present life into a house which was quiet and efficiently run, not like her own; and she would be able to go on working so that she and Bob could save up all money more quickly for their own house. She would also get Bob, a good enough husband for any working-class girl: good-natured and ready to be bent to her way whenever it was necessary for her ends.
Things went well until her mother-in-law’ s death, when Annie
A. had known Bob for a long time
B. wanted to leave home
C. was madly in love with Bob
D. had led a lonely life
