Task: Answer the multiple-choice question.
Query: Which compound exhibits a -0.701\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) C/C(CC(=O)Nc1ccccc1Cl)=N\NC(=O)C(=O)NCCO
b) O=C(Nc1ccc(N2CCOCC2)cc1)c1nc2ccccc2s1
Answer: a. C/C(CC(=O)Nc1ccccc1Cl)=N\NC(=O)C(=O)NCCO
