Task: Answer the multiple choice question.
Query: Which drug has a 15.842\% 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) CC(=O)c1nc(N2C(=O)C3CC=C(C)CC3C2=O)sc1C
b) O=c1c(Cc2ccccc2)c([O-])[n+](-c2ccc(Cl)cc2)c2ccc(-c3ccccc3)nn12
c) COc1ccc(/C=C(\NC(=O)c2cccs2)C(=O)Nc2ccc(C)cc2)cc1OC
Answer: a. CC(=O)c1nc(N2C(=O)C3CC=C(C)CC3C2=O)sc1C
