Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.538\% 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 other words.
Options:
a COc1cc(CNCC(C)C)cc(Br)c1OCC(=O)Nc1ccccc1.Cl
b COc1ccccc1C(=O)COC(=O)C(CCSC)NC(=O)COc1ccccc1
c Cc1ccc(OCC(=O)N2CCCCCCC2)cc1
d O=C(COc1ccccc1Cc1ccccc1)Nc1cccnc1
Answer: a. COc1cc(CNCC(C)C)cc(Br)c1OCC(=O)Nc1ccccc1.Cl
