Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.636\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. COc1ccc(CC(NC(C)=O)C(=O)NC2CCN(S(=O)(=O)c3ccc(NC(C)=O)cc3)CC2)cc1OC
b. O=C(CCNC(=O)Cn1ccc2ccccc2c1=O)NCCN1CCN(c2cccc(Cl)c2)CC1
c. CC1=CC(=O)C(C(C)C)=C/C1=N/OC(=O)c1cccc([N+](=O)[O-])c1
d. COc1ccccc1C(=O)NC(=Nc1nc2ccccc2o1)NC(=O)c1ccccc1OC
Answer: b. O=C(CCNC(=O)Cn1ccc2ccccc2c1=O)NCCN1CCN(c2cccc(Cl)c2)CC1
