Please help me. I have an idea of what the answer might be but I’m not sure so I need you to help me clarify if I was correct so please tell me what you think.

Hello!
According to the diagram, your answer is D.) Some Elephants have tusks
If the entire circle labeled "Elephants" was inside the circle labeled "Animals With Tusks," it would be A, but that is not the case. only part of it is inside. so D is the correct answer.
I hope this helps, and have a nice day!
