Task: Answer the multiple choice question.
Question: Which drug has a 18.293\% 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 other words.
Options:
[a] O=C1CC(Sc2nnc(-c3ccccc3)o2)C(=O)N1c1ccccc1
[b] O=C(N/N=C/c1ccccc1O)C1(O)c2ccccc2-c2ccccc21
[c] Cn1c(=O)c(=O)n(C)c2cc(S(=O)(=O)N3CCCC3C(=O)NCc3ccco3)ccc21
[d] C[C@H](NS(=O)(=O)c1ccccc1F)C(=O)OCC(=O)N1CCc2ccccc21
Answer: d. C[C@H](NS(=O)(=O)c1ccccc1F)C(=O)OCC(=O)N1CCc2ccccc21
