Task: Answer the multiple-choice question.
Query: Which compound exhibits a -1.117\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=c1cc(CSc2ccc([N+](=O)[O-])cc2)nc2sccn12
b: O=C(COC(=O)CCc1c[nH]c2ccccc12)NCc1ccccc1
c: O=C(O)C1CCCN1C(=O)Oc1ccccc1
d: CC12CCC(C(=O)Nc3nccs3)(OC1=O)C2(C)C
e: F[B-](F)(F)F.OCC[NH+]=c1cc(-c2ccccc2)oc2ccc(Cl)cc12
Answer: a. O=c1cc(CSc2ccc([N+](=O)[O-])cc2)nc2sccn12
