Task: Answer the multiple-choice question.
Query: Which drug has a 9.680\% 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: O=C(CN1CCN(c2ccccn2)CC1)Nc1ccccc1
b: O=C(CNC(=O)C1COc2ccccc2O1)N/N=C/c1ccc([N+](=O)[O-])cc1
c: COCC1CCN(C(=O)CCc2nnc(CCCCc3ccccc3)o2)CC1
d: Cc1c(N=Cc2ccc(-c3ccc(Cl)cc3)o2)c(=O)n(-c2ccccc2)n1C
Answer: c. COCC1CCN(C(=O)CCc2nnc(CCCCc3ccccc3)o2)CC1
