Task: Answer the multiple choice question.
Question: Which drug exhibits a 10.648\% 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(NC(=O)CCC(=O)c1cccs1)c1ccccc1
b: CC(C)Cn1nc(-c2ccccc2)c2ccccc2c1=O
c: COc1cc(CNCc2cc(OC)ccc2OC)cc(OC)c1.O=C(O)C(=O)O
d: Cc1ncc([N+](=O)[O-])n1Cc1ccc(F)cc1
e: CNc1ncc(C(=O)C(C)(C)C)s1
Answer: b. CC(C)Cn1nc(-c2ccccc2)c2ccccc2c1=O
