Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.380\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CCOc1ccc(C(C)=O)cc1CN1C(=O)NC2(CCCCC2C)C1=O
[b] C=C(c1ccc(OC)cc1)c1ccc(OC)cc1
[c] COc1cc(OC)c(NS(=O)(=O)c2cccc(C(=O)OCC(=O)NCC3CCCO3)c2)cc1Cl
Answer: a. CCOc1ccc(C(C)=O)cc1CN1C(=O)NC2(CCCCC2C)C1=O
