Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 16.625\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) CC(C)(C)C(=O)COc1ccccc1[N+](=O)[O-]
(b) Nc1nnc(SCc2coc(-c3ccc(Cl)cc3)n2)s1
(c) O=[N+]([O-])c1ccc(O)c(/C=N/n2cnc3ccccc32)c1
(d) CC(C)[C@H](N)c1nnc(SC/C=C/c2ccccc2)o1.Cl
(e) CC(=O)NCCC(=O)Nc1cc(F)ccc1C
Answer: c. O=[N+]([O-])c1ccc(O)c(/C=N/n2cnc3ccccc32)c1
