Which of the following is a consequence of the double standard of aging?

A) There are few romantic leads for middle-aged women actors.
B) Men are perceived as becoming old later than women.
C) A man is more likely to marry a younger woman than vice versa.
D) All of these answers are correct.

All of the given answers are consequences of the double standard of aging. Middle-aged women actors are often relegated to playing supporting roles or are sidelined from romantic leads (A). Men are perceived as becoming old later than women, and they are often celebrated as "distinguished" as they age, while women are expected to maintain their youth and beauty (B). This creates a societal expectation that men should marry younger women, and as a result, men are more likely to marry younger women (C).
