Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.129% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CC(=O)Nc1ccc(NC(=O)COc2ncnc3ccccc23)cc1
[b] CC(=O)Nc1ccc2c(c1)nc1n2CCN(C(C)c2ccccc2)C1
[c] CNC(=O)C1(C)C=CC2(CCCCC2)N1C(=O)OC
Answer: b. CC(=O)Nc1ccc2c(c1)nc1n2CCN(C(C)c2ccccc2)C1
