Task: Answer the multiple choice question.
Query: Which drug exhibits a 11.146\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. NS(=O)(=O)c1ccc(NC(=O)COC(=O)CCc2ccccc2)cc1
b. O=C(O)CC1=C(Nc2ccccc2)C(=O)N(c2ccccc2)C1c1ccc(Cl)cc1
c. CC1(C)OC(=O)C(=CNCCc2ccc(O)cc2)C(=O)O1
d. Cc1c(C(=O)Nc2ccc(Br)cc2)cnn1C
Answer: b. O=C(O)CC1=C(Nc2ccccc2)C(=O)N(c2ccccc2)C1c1ccc(Cl)cc1
