Task: Answer the MCQ question.
Question: Which drug exhibits a -6.929\% 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: COc1c(C(=O)Nc2ccc3[nH]c(=O)[nH]c3c2)cc2ccccc2c1Br
b: CC(NCc1ccc(S(N)(=O)=O)cc1)C(=O)Nc1ccc([N+](=O)[O-])cc1Cl
c: CC(C)(CO)NCc1cccs1.Cl
d: O=C(O)Cn1c2ccccc2c(=O)c2ccccc21
Answer: b. CC(NCc1ccc(S(N)(=O)=O)cc1)C(=O)Nc1ccc([N+](=O)[O-])cc1Cl
