Task: Answer the MCQ question.
Question: Which compound has a -1.406\% 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 or b without using any other words.
Options:
a. O=C(NCc1ccccn1)C1CCN(Cc2cccc(OCc3ccccc3)c2)CC1.O=C(O)C(=O)O
b. Cc1nn(CC(=O)Nc2cc(S(=O)(=O)N(C)C)ccc2Cl)c(C)c1[N+](=O)[O-]
Answer: a. O=C(NCc1ccccn1)C1CCN(Cc2cccc(OCc3ccccc3)c2)CC1.O=C(O)C(=O)O
