I’m really unsure about this one. I thought they might be part of the endocrine system, but now I’m questioning that.

I feel like I’ve seen a question like this before, and I think the tonsils are definitely not in the digestive system.

I remember studying that the tonsils help fight infections, so I’m leaning towards option D, the immune system.
