Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.851% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=c1c2ccccc2nc(/C=C/c2cc(Br)ccc2O)n1CCO
b) COc1ccc(CCC(=O)OCC(=O)N2CCN(S(=O)(=O)c3ccc(C)cc3C)CC2)cc1
c) Cc1ccc(-c2nc(C)sc2CC(=O)OCC(=O)Nc2cccc([N+](=O)[O-])c2)cc1
Answer: a. O=c1c2ccccc2nc(/C=C/c2cc(Br)ccc2O)n1CCO
