Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 12.905\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CC(Cc1ccccn1)NC(=O)c1ccc(OC2CCN(Cc3ccccn3)CC2)cc1
b: COC(=O)c1c(-c2ccccc2)c(-c2ccccc2)nn(C)c1=O
c: COc1ccc(NC(=O)CSc2nnc(CN3CCOCC3)n2C)cc1Cl
d: Brc1cccc(C2Nc3cccc4cccc(c34)N2)c1
Answer: b. COC(=O)c1c(-c2ccccc2)c(-c2ccccc2)nn(C)c1=O
