Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 0.667\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CC1=Nc2nc(N3CCCCC3)c(C#N)c3c4c(nc(c23)N1)N(c1ccc(C(C)C)cc1)C(=O)C4.CN(C)C=O
b: O=S(Cc1ccc(Cl)cc1)CC(O)(c1ccccc1)c1ccccc1
c: COc1ccc(N2CCN(C(=O)C34CCC(C)(C(=O)C3)C4(C)C)CC2)cc1
d: O=C(O)Cc1ccc(NC(=O)c2ccc(Cl)c(Cl)c2)cc1
Answer: c. COc1ccc(N2CCN(C(=O)C34CCC(C)(C(=O)C3)C4(C)C)CC2)cc1
