Task: Answer the multiple choice question.
Query: Which drug has a -18.277\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] c1cnc(SCCOc2cccc3ccccc23)nc1
[b] COc1ccc(CN2CCN(S(=O)(=O)c3ccccc3)CC2)c(OC)c1.O=C(O)C(=O)O
[c] Cc1ccccc1OCC(=O)Nc1ccc(NC(=O)c2ccco2)cc1
Answer: b. COc1ccc(CN2CCN(S(=O)(=O)c3ccccc3)CC2)c(OC)c1.O=C(O)C(=O)O
