Problem statement: Answer the multiple-choice question.
Query: Which drug has a 1.516\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(c1ccc(S(=O)(=O)N2CCCC2)cc1)N1CCN(c2ccccc2)CC1
b: O=C(CN1CCN(S(=O)(=O)c2ccc(Br)cc2)CC1)N/N=C/c1cc([N+](=O)[O-])ccc1Cl
Answer: b. O=C(CN1CCN(S(=O)(=O)c2ccc(Br)cc2)CC1)N/N=C/c1cc([N+](=O)[O-])ccc1Cl
