This question is incomplete since you have not provided information about the text it refers to. But either way I will help you with an explanation so that you can identify the answer for yourself.

Explanation:

The theme is the axis of a story, the concept around which our history revolves, which structures it. Far from being something concrete, the subject is an abstract concept, and must be able to be represented in a single word. It does not limit us to a space or to a specific time: starting from the same theme we can raise infinite stories.

Some possible topics, so you can get an idea, are love, hatred, pain, ambition, jealousy, narcissism, anguish, anger, infertility, hypochondria, heroism, cruelty ...

A story can have more than one theme, but there will always be one central theme that stands out from the others. That is the one you must identify in order to answer this question correctly.
