Problem statement: Answer the multiple choice question.
Question: Which compound has a 8.342\% 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 other words.
Options:
[a] CC(=O)N1CCCc2cc(S(=O)(=O)N3CCCC(C(=O)Nc4ccc(C)cc4C)C3)ccc21
[b] CCC(C)(C)NC(=O)c1cccc(NC(=O)C(C)C)c1
[c] CCn1c(C)c(C(C)=O)cc(C#N)c1=O
[d] CC1(C)COC(/C=C/c2cccc([N+](=O)[O-])c2)=N1
Answer: c. CCn1c(C)c(C(C)=O)cc(C#N)c1=O
