Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.589\% 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, or c without using any other words.
Options:
a) CCc1nn(C)c(-c2n[nH]c(=S)n2N)c1Cl
b) O=C(COC(=O)Cn1nnc2ccccc21)Nc1ccccc1Br
c) CC(=O)Nc1ccc(NC(=S)NC(=O)c2ccc([N+](=O)[O-])c(C)c2)cc1
Answer: b. O=C(COC(=O)Cn1nnc2ccccc21)Nc1ccccc1Br
