Task: Answer the multiple choice question.
Query: Which compound has a 10.568\% 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 other words.
Options:
a: CC(C)c1ccc(NC2CCCN(C(=O)CCN3CCCC3=O)C2)cc1
b: O=[N+]([O-])c1c(Nc2ccc(O)cc2)cc(Cl)c2nonc12
c: COc1ccccc1NC(=O)NC(=O)c1ccccc1
d: COc1cc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)ccc1OC(C)C
Answer: d. COc1cc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)ccc1OC(C)C
