Task: Answer the multiple choice question.
Query: Which compound exhibits a -16.025\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(NCCN1CCCCC1)c1cc(COc2c(F)cccc2F)on1
b: CS(=O)(=O)N(CC(=O)N1CCN(c2ccc(F)cc2)CC1)c1ccc(F)c(Cl)c1
c: COc1ccc(/C=C/c2c([N+](=O)[O-])c(=O)n(C)c(=O)n2C)cc1
Answer: b. CS(=O)(=O)N(CC(=O)N1CCN(c2ccc(F)cc2)CC1)c1ccc(F)c(Cl)c1
