Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.003\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CCN(CC)CC(C)C(C)OC(=O)C(O)(c1ccccc1)c1ccccc1.Cl
[b] COc1ccccc1OCc1ccc(C(=O)N2CCOCC2)o1
[c] COc1ccccc1C(CNC(=O)CCNC(=O)c1ccccc1Cl)N1CCCC1
Answer: a. CCN(CC)CC(C)C(C)OC(=O)C(O)(c1ccccc1)c1ccccc1.Cl
