Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.581\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CCOCCCNC(=O)CN1C2CCC1CC(O)(c1ccc(OC)cc1)C2
b: C=CCOC(=O)C1=C(C)OC(N)=C(C#N)C1c1c(C)nn(-c2ccccc2)c1Cl
c: COc1cccc(C=N[C@@H](CO)[C@@H](O)c2ccc([N+](=O)[O-])cc2)c1O
Answer: c. COc1cccc(C=N[C@@H](CO)[C@@H](O)c2ccc([N+](=O)[O-])cc2)c1O
