Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.165\% 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: O=[N+]([O-])c1cccc2c(S(=O)(=O)N3CCOCC3)cccc12
b: CSc1ccc(/C=C/C(=O)NC(=O)c2ccccc2O)cc1
Answer: a. O=[N+]([O-])c1cccc2c(S(=O)(=O)N3CCOCC3)cccc12
