I was torn between B) SYN flood and C) DDoS. But C feels right.

I think it's C) DDoS attack. It's definitely multi-tier.

I thought SYN flood was a multi-tier too, but I guess not?

I feel like the Smurf attack could be considered multi-tier since it uses multiple devices to amplify the attack, but I'm not confident.

I'm not entirely sure, but I remember something about SYN floods being more about overwhelming a single point rather than multi-tiered.

I think a DDoS attack is a multi-tier attack because it involves multiple systems targeting a single victim.
