Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.189\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] O=C(Nc1cc(S(=O)(=O)N2CCOCC2)ccc1N1CCOCC1)c1ccccc1F
[b] Cc1ccc(C(=O)O/N=C(\N)c2ccccc2)c(Cl)c1
[c] O=C(NCCCNC(=O)c1ccccn1)c1ccc(Br)cc1
[d] COc1ccc(C(=O)C[n+]2cc(-c3ccc(OC)cc3)n3c2CCCC3)cc1.[Br-]
[e] COC(=O)C1=C(C)NC(=S)NC1c1ccc(OCC(=O)N2CCCCC2)c(OC)c1
Answer: c. O=C(NCCCNC(=O)c1ccccn1)c1ccc(Br)cc1
