Task: Answer the multiple choice question.
Question: Which compound exhibits a -29.538% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a COc1ccc(CNC(=O)Nc2cc(C)cc(C)c2)cc1
b Cc1cccc(OCc2nc(C#N)c(N3CCCC3)o2)c1
c OC[C@@H](O)[C@H](O)C(/C=N/Nc1ccccc1)=N\Nc1ccccc1
d COc1ccc(OC)c(Nc2nc(-c3cccs3)cs2)c1
Answer: b. Cc1cccc(OCc2nc(C#N)c(N3CCCC3)o2)c1
