Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -19.375% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cc1ccc(CN2CCN(/N=C/c3cc(Br)ccc3O)CC2)cc1
b: CN(CC(=O)Nc1ccccc1Br)C(=O)c1sccc1-c1ccccc1
c: C[N+](C)(C)CCOP(=O)([O-])OC[C@H](O)CO
Answer: b. CN(CC(=O)Nc1ccccc1Br)C(=O)c1sccc1-c1ccccc1
