Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.289\% 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 other words.
Options:
a O=[N+]([O-])c1ncn(CCn2cnc([N+](=O)[O-])n2)n1
b Cl.OCCNc1nc(NCc2ccccc2)c2ccccc2n1
c c1ccc(Cn2ccnc2SCc2nnc(-c3ccccc3)o2)cc1
d COc1cccc(CNC(=O)CCCn2nc(C)n3c(cc4sccc43)c2=O)c1
e O=C(COC(=O)c1ccccc1NC(=O)c1ccco1)NCCC1=CCCCC1
Answer: a. O=[N+]([O-])c1ncn(CCn2cnc([N+](=O)[O-])n2)n1
