Task: Answer the multiple choice question.
Query: Which compound exhibits a -77.598\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. CC(C)CC(=O)c1c[nH]c(C(=O)O)c1
b. O=[N+]([O-])c1ccc(OCC(O)CN2CCN(c3ccccc3F)CC2)cc1
c. O=C(NCCO)c1cc2c([nH]c3ccccc32)c(-c2ccccc2)n1
d. COc1ccc(-c2cc3c(=O)n(CC(=O)NCc4ccc(Cl)cc4)ncn3n2)cc1
e. COc1ccc(Cl)cc1NC(=O)CN(C)C(=O)c1ccc(C)s1
Answer: b. O=[N+]([O-])c1ccc(OCC(O)CN2CCN(c3ccccc3F)CC2)cc1
