Hmm, I thought sniffers worked at the Session layer to monitor network traffic. I'm going with B.

Wait, isn't a sniffer supposed to be a hacker tool? I'm pretty sure it's in the Network layer, so A must be the right answer.

A sniffer operates at the Data Link layer, so I think the correct answer is D.

I'm not sure, but I think it might be the Network layer because it deals with routing and forwarding of data.

I agree with Reita, because a sniffer captures data packets at the network interface level.
