Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.492% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C1OC(CCl)CN1Cc1c(Cl)cccc1Cl
b: CC(=O)Nc1cccc(NC(=O)c2ccc3c(c2)CCN3S(=O)(=O)c2ccccc2)c1
c: COc1cc(/C=C2/SC(=S)N(Cc3ccccc3)C2=O)cc(OC)c1O
d: O=C1N(Cc2cccc(Cl)c2)C[C@@H]2C[C@@H](c3ccco3)N3CCC[C@@]123
Answer: a. O=C1OC(CCl)CN1Cc1c(Cl)cccc1Cl
