I’m guessing this is a simple sentence sorry if I’m wrong good luck.
Answer: Their
Explanation:
Their = belonging to or associated with the people or things previously mentioned or easily identified.
Assuming the options are crowded out, rich flora, plunge pool, or flowing stream, the answer would be <u>crowded out</u>. This implies that there isn't enough room for something, a negative idea, whereas the others describe nature.
This is an internal conflict. It is internal because the person in it is struggling whether to do what the person wants to do or what is expected of the person. External would be between people and not between multiple parts of a single person.
