Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.751\% 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] COC(=O)COc1ccc(S(=O)(=O)N2CCOCC2)cc1C
[b] O=C(COC(=O)CCCNC(=O)c1ccc(Cl)cc1)NCc1ccccc1Cl
[c] COc1cc(/C=N/N=C2/C(=O)Nc3ccccc32)cc(OC)c1O
[d] COc1ccc(Cl)cc1NC(=O)C/C(C)=N/NC(=O)CC#N
Answer: c. COc1cc(/C=N/N=C2/C(=O)Nc3ccccc32)cc(OC)c1O
