Task: Answer the multiple-choice question.
Question: Which drug exhibits a 15.830\% 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, c, or d without using any additional words.
Options:
a. COc1ccc2sc(SCCCS(=O)(=O)O)[n+](CCCS(=O)(=O)[O-])c2c1
b. CCC(C)(C)NC(=O)C(c1ccccc1Cl)N(C(=O)CCC(=O)Nc1cc(C)on1)c1ccc(NC(C)=O)cc1
c. CCN1C(=NCc2ccco2)N[C@@H](c2cccc(F)c2)C(C(=O)OC)=C1C
d. CC(=O)Oc1ccc(C(C)=O)c2c1OCCO2
Answer: a. COc1ccc2sc(SCCCS(=O)(=O)O)[n+](CCCS(=O)(=O)[O-])c2c1
