Task: Answer the MCQ question.
Question: Which compound exhibits a 13.418\% 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 other words.
Options:
[a] O=C1CC(c2ccco2)CC(O)=C1C=NCC1CCNCC1
[b] Cc1cccc(CN2C[C@]34CC[C@@H](C[C@@H]3S2(=O)=O)O4)c1
[c] CCN(c1ccccc1)S(=O)(=O)c1cccc(C(=O)NCc2ccccn2)c1
Answer: a. O=C1CC(c2ccco2)CC(O)=C1C=NCC1CCNCC1
