Problem statement: Answer the multiple-choice question.
Question: Which drug has a 9.620\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1ccc(NC(=O)CCc2c(C)nn(-c3ccc(N4CCOCC4)nn3)c2C)cc1
b CCOC(=O)c1c(NC(=O)Nc2ccc(C)cc2)sc2c1CCN(C)C2
c CN(C)C(=S)NC(=NCc1ccc([N+](=O)[O-])cc1)c1ccccc1
d O=C(c1ccc2ccccc2c1)N1CCN(c2ccc([N+](=O)[O-])c(N3CCOCC3)c2)CC1
Answer: b. CCOC(=O)c1c(NC(=O)Nc2ccc(C)cc2)sc2c1CCN(C)C2
