Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.640\% 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: COc1ccc(C(=O)N2CCN(C(=O)CC(C)C)CC2)cc1OC
b: CC1(C)Cc2c(cnn2-c2ccccc2)C(=O)/C1=N\NC(=O)c1ccccc1O
c: Cc1cccc(CCNC(=O)CCCOc2cc(=O)n(C)c3ccccc23)c1
Answer: b. CC1(C)Cc2c(cnn2-c2ccccc2)C(=O)/C1=N\NC(=O)c1ccccc1O
