I thought antigens were just for digestion? This is new info for me!

Wait, are we sure about that? I thought they could suppress responses too.

I’m a bit confused because I thought antigens could also suppress responses, but that might be a different concept. I’ll stick with A for now.

I feel like I’ve seen a question like this before, and I think it was about how antigens stimulate the immune response. So, A seems right to me.

I remember something about antigens triggering responses, but I’m not completely sure if it’s just A or if there’s more to it.

I think antigens are related to the immune system, so I’m leaning towards option A.

Wait, I thought antigens were something that suppressed the immune system. Maybe I'm getting that mixed up with something else. I better double-check my notes before answering this.

Okay, I've got this. Antigens are the foreign substances that our immune system recognizes and responds to. So option A, "a substance that stimulates an immune response," is the correct answer.

This one seems pretty straightforward. Antigen is a substance that triggers an immune response, so I'm going with option A.

Hmm, I'm a little unsure about this one. I know antigens have something to do with the immune system, but I can't quite remember the exact definition. I'll have to think this through carefully.

The wording on some of these options is tricky. I'll need to analyze each one closely to determine which ones are actually true.

C'mon, it's obviously A. Antigens are like the supervillains of the body - they're here to cause trouble, not help with digestion or muscle movement. I bet the person who wrote this question was feeling a little 'antsy' that day.
