Task: Answer the multiple choice question.
Question: Which drug has a 14.153\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(COC(=O)c1cc([N+](=O)[O-])ccc1NCc1ccccc1)NCc1ccccc1Cl
(b) Cn1nc(C(=O)Nc2cccc(S(=O)(=O)N3CCCC3)c2)c2ccccc2c1=O
(c) COc1ccc2c(c1)-c1c(sn(-c3ccccc3)c1=S)C(C)(C)N2
Answer: a. O=C(COC(=O)c1cc([N+](=O)[O-])ccc1NCc1ccccc1)NCc1ccccc1Cl
