Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 10.945\% 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: COc1ccc(N(CC(=O)NCCC2=CCCCC2)S(=O)(=O)c2ccc(C)cc2)cc1
b: O=c1c2c(-c3cccc([N+](=O)[O-])c3)ccnc2[nH]n1-c1ccccc1
Answer: b. O=c1c2c(-c3cccc([N+](=O)[O-])c3)ccnc2[nH]n1-c1ccccc1
