Task: Answer the multiple choice question.
Question: Which compound exhibits a -21.755% 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=C(/C=C/c1cccc([N+](=O)[O-])c1)NCCc1ccc(F)cc1
b: C[C@@H](C(=O)NCc1ccccn1)[C@H]1C[C@]1(C)[C@H](NC(=O)OCc1ccccc1)c1ccccc1
c: COc1ccc(N2CC(C(=O)OCC(=O)c3ccccc3)CC2=O)cc1
d: O=C(CCCn1c(SCC(=O)c2ccc(F)cc2)nc2ccccc2c1=O)NCc1ccccc1
Answer: a. O=C(/C=C/c1cccc([N+](=O)[O-])c1)NCCc1ccc(F)cc1
