Problem statement: Answer the multiple choice question.
Question: Which drug has a 2.437\% 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] O=CN1CCN(C(=O)CC(c2ccccc2)c2cc(Br)ccc2O)CC1
[b] CN1CCN(NC(=O)CN2C(=O)/C(=C/c3ccccc3Cl)SC2=S)CC1
[c] CC(=O)Nc1ccc(S(=O)(=O)Nc2ccc(C)c([N+](=O)[O-])c2)cc1
Answer: a. O=CN1CCN(C(=O)CC(c2ccccc2)c2cc(Br)ccc2O)CC1
