Task: Answer the multiple choice question.
Query: Which compound exhibits a -9.754\% 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. COC(=O)C1=C[C@@H](C(=O)OC)[C@@H]2C3=C(C(=O)C2(C)C)[C@H](C)n2c(=O)n(-c4ccccc4)c(=O)n2[C@@H]3C1
b. O=C(NCc1ccc(F)cc1)c1ccc(N2CCOCC2)c([N+](=O)[O-])c1
c. CCOc1ccccc1NC(=O)NNS(=O)(=O)c1cc(OC)ccc1OC
d. COc1cccc(NC(=O)c2ocnc2C)c1
Answer: b. O=C(NCc1ccc(F)cc1)c1ccc(N2CCOCC2)c([N+](=O)[O-])c1
