Task: Answer the multiple-choice question.
Query: Which compound exhibits a 17.896\% 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 other words.
Options:
a: O/N=C1\CCCc2c1nc(-c1ccccc1F)n2O
b: OCCCc1nc2ccccc2n1CCc1ccccc1
c: CC1C/C(=N\Nc2ccc(S(N)(=O)=O)cc2[N+](=O)[O-])CC(C)(C)C1
d: CCOC(=O)C1=C(C)NC(=O)NC1c1ccc(-c2ccc(Cl)cc2)o1
Answer: a. O/N=C1\CCCc2c1nc(-c1ccccc1F)n2O
