Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.044\% 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 additional words.
Options:
(a) CCN(CC)S(=O)(=O)c1ccc(Cl)c(C(=O)Nc2ccc(Cl)cc2[N+](=O)[O-])c1
(b) O=C(CCc1ccccc1)NCc1cccnc1
Answer: a. CCN(CC)S(=O)(=O)c1ccc(Cl)c(C(=O)Nc2ccc(Cl)cc2[N+](=O)[O-])c1
