Task: Answer the multiple choice question.
Query: Which compound exhibits a 5.403\% 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 other words.
Options:
a) O=C(COc1ccccc1Cl)Nc1ccc(CN2CCOCC2)cc1
b) Cc1cc(-c2cc(-c3ccc(Cl)cc3)nc(N)c2C#N)co1
c) C=CCN1C(=O)C(CC(=O)Nc2ccc(OCCC)cc2)N(CCCN2CCN(Cc3ccccc3)CC2)C1=S
Answer: a. O=C(COc1ccccc1Cl)Nc1ccc(CN2CCOCC2)cc1
