Task: Answer the multiple-choice question.
Question: Which compound exhibits a 2.725\% 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] Cc1cc(C)c(NC(=S)N(CCc2ccncc2)C(C)C)c(C)c1
[b] COc1ccc(CCNC(=O)c2ccc3c(c2)NC(=O)C(CSCc2cc(C)ccc2C)N3)cc1OC
[c] Cc1cc(C(C)(C)C)cc(S(=O)(=O)Nc2cccc(C(=O)O)c2)c1C
[d] O=C(Cn1nnc(-c2ccccc2)n1)N/N=C/c1cccc([N+](=O)[O-])c1
Answer: d. O=C(Cn1nnc(-c2ccccc2)n1)N/N=C/c1cccc([N+](=O)[O-])c1
