Task: Answer the multiple choice question.
Question: Which compound exhibits a -6.163\% 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, or c without using any additional words.
Options:
[a] O=C(COC(=O)c1cc[n+]([O-])cc1)NCc1ccccc1Cl
[b] Cc1ccc(-n2ncc3c(NNC(=O)Cc4ccccc4)ncnc32)cc1
[c] Cc1cc(C)n(Cc2ccc(C(=O)NN)o2)n1
Answer: a. O=C(COC(=O)c1cc[n+]([O-])cc1)NCc1ccccc1Cl
