Task: Answer the multiple choice question.
Question: Which compound has a 16.634\% human ether-à-go-go related gene (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] Cc1ccc(C)c(NC(=O)CN2C(=O)CNC2=O)c1
[b] O=C1NC[C@H](c2ccccc2)N(CCC23CC4CC(CC(C4)C2)C3)C1=O
[c] COc1cc(CN2CC(=O)N(c3ccc(C)cc3)C2=S)cc(OC)c1OC
[d] COc1ccc(OC)c(C2C(C#N)=C(N)N(N(C)C)C3=C2C(=O)CCC3)c1
Answer: b. O=C1NC[C@H](c2ccccc2)N(CCC23CC4CC(CC(C4)C2)C3)C1=O
