Related-key attack? Isn't that like when the attacker has a VIP pass to the crypto party, and they can try on all the different key outfits until they find the perfect match?

I'm not sure, but I think it could also be A) Adaptive chosen-ciphertext because the attacker can observe the cipher under different keys.

I agree with Merri, Related-key makes sense because the attacker knows some mathematical relationship between the keys.
