Task: Answer the multiple-choice question.
Question: Which drug has a -20.234% 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: COc1ccc(C(=O)Oc2cc(/C=N/NS(=O)(=O)c3ccccc3)ccc2OC)cc1
b: O=C(Nc1cccnc1)c1cc(-c2cc(Cl)ccc2O)n[nH]1
c: C=CCN(CC=C)C(=O)CN1C(=O)NC(c2ccccc2)(c2ccccc2)C1=O
Answer: c. C=CCN(CC=C)C(=O)CN1C(=O)NC(c2ccccc2)(c2ccccc2)C1=O
