Correct Option: C. Ada Detailed Explanation: In the novel The Life Changer, the character of Salma's roommate who is described as reserved and withdrawn yet generous to a fault is Ada. Let's break down why Ada fits this description and analyze the other options.

1. Understanding the Character Traits:
2. Reserved and Withdrawn: This means that the character tends to keep to themselves, is not very outgoing, and may not engage much in social interactions. They might be shy or prefer solitude.
3. Generous to a Fault: This phrase indicates that the character is very giving and kind-hearted, often putting others' needs before their own, sometimes to the point of neglecting their own well-being.
4. Ada's Character in the Novel:
5. Ada is portrayed as someone who, despite her quiet nature, shows immense kindness and generosity towards her friends and those around her. Her reserved demeanor does not hinder her ability to care deeply for others, making her a complex and relatable character.
6. Throughout the story, Ada's actions demonstrate her willingness to help others, even when it may not be convenient for her. This duality of being both reserved and generous is a significant aspect of her character development.

Analysis of Other Options:

• A. Ngozi:
• While Ngozi may have her own traits, she is not primarily characterized as reserved or withdrawn. Instead, she often displays a more outgoing personality, which contrasts with the description given in the question. Therefore, she does not fit the criteria of being both reserved and generous.
• B. Tomiwa:
• Tomiwa is another character who may exhibit different traits. He is not typically described as reserved; rather, he is more expressive and engaged with others. His character does not align with the specific combination of traits mentioned in the question.
• D. None of them:
• This option suggests that none of the characters fit the description. However, since Ada clearly embodies the traits of being reserved and generous, this option is incorrect.

Summary of Key Points:

• Ada is the character who is both reserved and generous, making her the correct answer.
• Ngozi and Tomiwa do not fit the description due to their more outgoing personalities.
• The option "none of them" is incorrect because Ada meets the criteria outlined in the question.

Revision Summary:

• Ada is Salma's roommate who is reserved and generous.
• Understanding character traits is crucial for analyzing literature.
• Evaluate each character's actions and personality to determine their fit for specific descriptions.
• Always consider the context of the characters within the story to make informed choices.
