Final answer:
Charlotte Lucas is a pragmatic character from Jane Austen's Pride and Prejudice who marries Mr. Collins for security rather than love, contrasting with protagonist Elizabeth Bennet.
Step-by-step explanation:
Charlotte Lucas is a character in Jane Austen's novel Pride and Prejudice. She is Elizabeth Bennet's close friend and is known for her pragmatic and unromantic approach to marriage.
In contrast to Elizabeth's desire for a marriage based on love, Charlotte believes security and social standing are more important; thus, she marries Mr. Collins for his offer of a stable home and position, despite lacking romantic feelings for him.
Charlotte's character serves as a foil to Elizabeth, highlighting differing attitudes toward marriage in the society of that time.
