Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.193\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COc1ccc(N(CC(=O)Nc2ccc3c(c2)OCO3)S(C)(=O)=O)c(OC)c1
[b] CCOc1cc(CNCc2ccccn2)ccc1OCC(=O)NC1CCCCC1.Cl
[c] O=C(CN1CCOCC1)Nc1scc2c1c(=O)oc1ccccc12
[d] COC(=O)c1ccc(NC2CC(=O)N(c3ccccc3C)C2=O)cc1
Answer: c. O=C(CN1CCOCC1)Nc1scc2c1c(=O)oc1ccccc12
