Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -18.036% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCc1cc(-c2[nH]ncc2-c2ccc([N+](=O)[O-])cc2)c(O)cc1OC
(b) O=NN(CCCl)C(=O)NCCCl
Answer: a. CCc1cc(-c2[nH]ncc2-c2ccc([N+](=O)[O-])cc2)c(O)cc1OC
