Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.843\% 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] CNC(=O)CC(C(=O)O)c1ccc(OCC(C)C)cc1
[b] COc1ccc(C2C(C(=O)c3ccco3)=C(O)C(=O)N2CCc2ccccc2)cc1OC
[c] O=C(O)c1cc(NC(=O)C2CCCO2)cc(NC(=O)C2CCCO2)c1
[d] O=c1oc2c(CN3CCOCC3)c(O)c(Cl)cc2c2c1CCCC2
Answer: a. CNC(=O)CC(C(=O)O)c1ccc(OCC(C)C)cc1
