Task: Answer the multiple choice question.
Query: Which compound exhibits a 13.978\% 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: CN1CCN(C(=O)C2CCCN(S(=O)(=O)c3ccc(Cl)cc3)C2)CC1
b: O=C(COC(=O)C1CC1)NCc1ccccc1Cl
c: Cc1c(N=Nc2c(O)n(Cc3ccccc3)c(=O)[nH]c2=O)c(=O)n(-c2ccccc2)n1C
d: Cn1c(NC(=O)c2cccs2)c(-c2cccs2)c(=O)c2ccccc21
Answer: b. O=C(COC(=O)C1CC1)NCc1ccccc1Cl
