Which of the Following Is the BEST Summary of Research

Which of the following is the BEST summary of research findings on changes in sexual behaviour in older adulthood?

A) After the age of 65,interest in sexual activity drastically declines resulting in an equally drastic decline in sexual activity.Thus,most older adults no longer have sex.
B) After the age of 60,men continue to be interested in sex but women lose their interest in sex almost entirely.Thus,in older adulthood men have much higher rates of sexual activity than do women.
C) After the age of 60,many men and women experience a decreased interest in sex resulting in a slight decrease in the frequency of sexual activity.Despite this,most men and women continue to have sex throughout older adulthood.
D) After the climacteric and andropause,men and women are no longer biologically capable of becoming sexually aroused.Thus,sexual behaviours in older adulthood are replaced with affectionate behaviours.
