Task: Answer the multiple choice question.
Question: Which compound has a 9.337\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) COCCCn1c(SCC(=O)Nc2cccc(C(=O)OC)c2)nnc1-c1ccncc1
(b) CCOC(=O)N1CCN(c2c(NCCCN(CC)CC)c(=O)c2=O)CC1
(c) CCCC(C)C(=O)Nc1ccc(S(N)(=O)=O)cc1
(d) C/C(N)=C(/C#N)C(=O)COC(=O)c1ccc(C#N)cc1
(e) NC(Cc1ccc(O)c([N+](=O)[O-])c1)C(=O)O
Answer: b. CCOC(=O)N1CCN(c2c(NCCCN(CC)CC)c(=O)c2=O)CC1
