Task: Answer the multiple-choice question.
Question: Which compound has a 4.662\% 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] Cn1nnnc1SCc1csc(C2C(C#N)=C(N)OC3=C2C(=O)CCC3)c1
[b] COc1ccc2c([N+](=O)[O-])c(Cl)[nH]c2c1
[c] CC(=O)Nc1ccc(OCC(=O)c2ccc(C)cc2C)cc1
[d] CCOC(=O)C1(Cc2cccc(Cl)c2)CCCN(C(=O)c2cccc(C)n2)C1
[e] Cc1nn(C)cc1/C=N\NC(=O)c1csc2c1CCCC2
Answer: a. Cn1nnnc1SCc1csc(C2C(C#N)=C(N)OC3=C2C(=O)CCC3)c1
