Task: Answer the multiple-choice question.
Question: Which compound has a 0.456\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CC(=O)N1[C@@H]2CC3C4CC=C5C[C@@H](O)CC[C@]5(C)C4CC[C@]3(C)[C@@]21C(C)=O
b: CC(C)c1ccccc1-n1cc[nH]c1=S
c: Cc1ccc(-n2nccc2-c2cc(Cl)sc2Cl)cc1
Answer: a. CC(=O)N1[C@@H]2CC3C4CC=C5C[C@@H](O)CC[C@]5(C)C4CC[C@]3(C)[C@@]21C(C)=O
