Task: Answer the multiple-choice question.
Question: Which drug exhibits a -18.414% 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 other words.
Options:
a: O=C(COC(=O)/C=C/c1ccc([N+](=O)[O-])cc1)NC(c1ccccc1)c1ccccc1
b: OC(CSc1ccccc1Cl)CN1CCN(c2ccc(F)cc2)CC1
c: CC(C)(C)c1ccc(C(=O)NCCOc2ccccc2)cc1
d: C[C@H](NC(=O)C(c1ccccc1)c1ccccc1)c1ccccc1
Answer: a. O=C(COC(=O)/C=C/c1ccc([N+](=O)[O-])cc1)NC(c1ccccc1)c1ccccc1
