Task: Answer the multiple-choice question.
Query: Which drug exhibits a 0.973\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1ccc(C(C(=O)NC(C)(C)C)N(Cc2cccs2)C(=O)CCC(=O)Nc2cc(C)on2)cc1
b: CC(C)[C@@H](COc1ccccc1)N1CCN(Cc2ccccc2)CCC1=O
c: Cc1cc(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)(C)C3)c(C)s1
d: O=C(Nc1ccc(Cl)cc1)C1=Cc2cc(Cl)ccc2OC1
e: O=C(CN1C(=O)CSc2ncccc21)NCCN1CCOCC1
Answer: b. CC(C)[C@@H](COc1ccccc1)N1CCN(Cc2ccccc2)CCC1=O
