Task: Answer the multiple choice question.
Query: Which drug has a 13.246\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CN(Cc1c(F)cccc1Cl)C(=O)CNC(=O)c1cccs1
b: O=C(CNC(=O)c1ccc(Cl)cc1)OCC(=O)N1CCCC1
c: COc1ccc(-c2nnc(NC(=O)c3ccc4c(c3)OCCO4)o2)cc1
d: CCC(C)NC(=O)C1CCN(S(=O)(=O)c2cc([N+](=O)[O-])ccc2Cl)CC1
Answer: c. COc1ccc(-c2nnc(NC(=O)c3ccc4c(c3)OCCO4)o2)cc1
