Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 6.961\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COCCSc1nnc(NC(=O)Cc2ccc(OC)c(OC)c2)s1
[b] COC(=O)C1=C(C(=O)OC)C(c2cc([N+](=O)[O-])ccc2O)c2sc(=O)[nH]c2S1
[c] Cc1ccc(C(=O)Nc2cccc(NC(=O)CN3CCCCC3)c2)cc1
[d] Cc1ccc(S(=O)(=O)N2C(=O)CCC2C(=O)Nn2cnnc2)cc1
Answer: b. COC(=O)C1=C(C(=O)OC)C(c2cc([N+](=O)[O-])ccc2O)c2sc(=O)[nH]c2S1
