Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 13.999\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCN(CC)S(=O)(=O)c1ccc2oc(Nc3ccccc3)nc2c1
(b) CCOC(=O)CSc1nnc(CNC(=O)c2ccc(OC)cc2OC)n1-c1ccc(OC)cc1
Answer: a. CCN(CC)S(=O)(=O)c1ccc2oc(Nc3ccccc3)nc2c1
