Answer and Explanation:
Charlotte: even though Charlotte comes from a good family - not wealthy, but good - she is not considered a beauty. At the age of 27, her prospects for marriage are not that good. And the older she gets, the less likely it is for her to find a husband. However, she does find one: Mr. Collins. A revelation about their engagement is the fact that Charlotte is not a romantic woman. She does not love Mr. Collins, and she is not concerned about that. All that matters to her is getting married and living a comfortable life which, even though strange for our current standards, was pretty much all women cared about back then, especially if they were not rich.
Jane: is the eldest Bennet sister and one of the most beautiful girls, and certainly the sweetest, in the area. Jane quickly has a wealthy man, Mr. Bingley, fall in love with her. Her prospects seem good, but then, for a while, Mr. Bingley is convinced to not marry her. The issue is her family, which is filled with eccentric characters. They do get married in the end, and seem to live happily together. Unlike Charlotte, Jane wants to marry for love, which she does. She cannot imagine herself tied to a man whom she does not love.
Elizabeth: the main character, and the second oldest Bennet sister, is smart, pretty, and good humored. Her prospects for marriage are also good, even if not as much as her sister's at first. However, her family again serves as a hindrance since Mr. Darcy, even though in love with Elizabeth, does not like her family's manners and behaviors. In the end they too get married and live happily. Similarly to Jane, Elizabeth would rather marry for love. But for her, respect is also something fundamental for marital happiness.
