Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 27.635% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(COC(=O)c1cccc([N+](=O)[O-])c1)c1ccc(OCc2ccccc2)cc1
b: COc1ccc(CCNC(=O)c2cc([N+](=O)[O-])ccc2N2CCOCC2)cc1
Answer: a. O=C(COC(=O)c1cccc([N+](=O)[O-])c1)c1ccc(OCc2ccccc2)cc1
