Task: Answer the multiple choice question.
Question: Which compound has a 12.774\% 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 CCN(CC)CCn1c2c(c(SCC(=O)Nc3ccccc3Cl)nc1=O)CCC2
b C=C(C)CSc1nc(N)c(C#N)c(-c2ccc(C)cc2)c1C#N
c Cc1cc(C)nc(NCCCN2CCOCC2)n1
Answer: b. C=C(C)CSc1nc(N)c(C#N)c(-c2ccc(C)cc2)c1C#N
