Task: Answer the MCQ question.
Question: Which compound exhibits a -0.789\% 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 CCN1C(=NCCOC)N[C@@H](c2cccs2)C(C(=O)OC)=C1C
b COc1ccc(OCC(O)CNC(=O)Nc2ccccc2)cc1
c Cc1c(C)c2ccc(OCC(=O)N3CCC(C(=O)O)(c4ccccc4)CC3)cc2oc1=O
Answer: a. CCN1C(=NCCOC)N[C@@H](c2cccs2)C(C(=O)OC)=C1C
