Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 21.768\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CCOC(=O)c1cc(-c2ccccc2)sc1NC(=O)CN1C(=O)c2ccccc2C1=O
b: COc1cccc(-c2nc(CCl)cs2)c1OC.Cl
c: CN(C)/C(=N\S(=O)(=O)c1ccccc1)c1ccc([N+](=O)[O-])cc1
Answer: c. CN(C)/C(=N\S(=O)(=O)c1ccccc1)c1ccc([N+](=O)[O-])cc1
