Problem statement: Answer the multiple choice question.
Question: Which drug has a 21.140% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1ccc(Cn2nnnc2C(c2cccs2)N2CCN(c3ccc([N+](=O)[O-])cc3)CC2)cc1
(b) CC1CCN(c2ccccc2NC(=O)c2ccc(F)cc2)CC1
(c) O=c1[nH]c2cc(Cl)ccc2o1
Answer: c. O=c1[nH]c2cc(Cl)ccc2o1
