Task: Answer the multiple-choice question.
Question: Which drug exhibits a 0.594\% 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 additional words.
Options:
[a] CC(=O)OCC(=O)Nc1ccc(C(C)=O)cc1
[b] O=C(O)c1ccc(NNC(=S)Nc2cc(C(F)(F)F)ccc2Cl)cc1
[c] O=C1N(Cc2cccc(Cl)c2)C[C@@H]2C[C@@H](c3cccn3-c3cccnc3)N3CCC[C@@]123
[d] COCCN(C(=O)Nc1ccc(OC)cc1)c1nc2ccccc2s1
Answer: a. CC(=O)OCC(=O)Nc1ccc(C(C)=O)cc1
