Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.933\% human ether-à-go-go related gene (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 additional words.
Options:
a O=[N+]([O-])c1ccc(/C([O-])=C(/C(=S)Nc2ccccc2F)[n+]2ccccc2)cc1
b O=C(COC(=O)CNC(=O)c1ccc(Br)cc1)NCCC1=CCCCC1
c O=C(c1ccccc1F)N1CCN(c2ccc([N+](=O)[O-])c(N3CCOCC3)c2)CC1
d COc1cc(N)c(Cl)cc1C(=O)OC(C)C(=O)Nc1cccc(S(=O)(=O)N2CCOCC2)c1
Answer: a. O=[N+]([O-])c1ccc(/C([O-])=C(/C(=S)Nc2ccccc2F)[n+]2ccccc2)cc1
