The statement that best reflects a theme of the passage is:
B. Two people may see a situation differently.
This theme is evident as Stacia and Tasha have different perspectives on their friendship and the contributions each has made to various projects. Stacia feels that Tasha takes credit for her ideas, while Tasha believes she is helping Stacia by sparing her the attention. Their contrasting views highlight the complexity of relationships and misunderstandings.
