Task: Answer the multiple choice question.
Question: Which drug has a 7.494\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(c1ccc([N+](=O)[O-])cc1[N+](=O)[O-])N1CCN(C(=O)C2CCCO2)CC1
[b] O=C(COC(=O)c1cccs1)Nc1ccccc1
[c] O=C(CCc1nnc2ccc(N3CCCC3)nn12)Nc1cc(F)ccc1F
[d] CCOC(=O)NC(=O)c1cn(Nc2ncc(C(F)(F)F)cc2Cl)c(=O)[nH]c1=O
Answer: a. O=C(c1ccc([N+](=O)[O-])cc1[N+](=O)[O-])N1CCN(C(=O)C2CCCO2)CC1
