Hello. You did not present the text that this question refers to, nor did you present the answer options. This makes it impossible for your question to be answered. However, I will try to help you as best I can.
An internal conflict is very easy to identify in a text, as this is a conflict that the character has with himself, with his own thoughts. This character may be confused, suspicious, with contradictory thoughts, or even the character may be trying not to think or act in a certain way. In this case, we can say that an internal conflict is a conflict that the character has with his own emotions, feelings and thoughts. Therefore, to answer this question, you must read the text and identify this type of fight that the character is presenting.
