Task: Answer the multiple-choice question.
Question: Which compound exhibits a 1.971% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] O=C(CSc1nc2ccc(NC(=O)CSc3nnnn3-c3ccccc3)cc2s1)Nc1ccccc1
[b] Cc1nnc(NC(=O)CSc2nnc(C)c(=O)n2N)s1
[c] COc1ccc(-c2nnc(SCC(=O)O)n2Cc2ccccc2)cc1
[d] Cn1c2c(c(=O)n(C)c1=O)C(c1ccccc1F)C(C#N)=C(N)O2
[e] Cc1ccc(-c2noc(C3CCCN(C(=O)C4CCCCC4)C3)n2)o1
Answer: b. Cc1nnc(NC(=O)CSc2nnc(C)c(=O)n2N)s1
