Correct answer: C — Aminosteroids

Aminosteroidal NMBAs: rocuronium / vecuronium / pancuronium (reversed by sugammadex). Benzylisoquinolinium NMBAs: atracurium / cisatracurium / mivacurium (NOT reversed by sugammadex). The structural class determines metabolism pathway and susceptibility to sugammadex reversal.
