Task: Answer the multiple-choice question.
Query: Which compound has a -3.907\% 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: Cc1ccc(N(CC2CO2)S(=O)(=O)c2ccc([N+](=O)[O-])cc2)cc1
b: O=C(c1cc(COc2ccc(F)cc2F)on1)N1CC[C@@H]2CCCC[C@H]2C1
Answer: a. Cc1ccc(N(CC2CO2)S(=O)(=O)c2ccc([N+](=O)[O-])cc2)cc1
