Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.042\% 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: CCOc1ccc2nc(NCCCNS(=O)(=O)c3ccc(C)cc3)c(C#N)cc2c1
b: CCC/C=N/NC(=O)c1cc(Br)ccc1O
Answer: a. CCOc1ccc2nc(NCCCNS(=O)(=O)c3ccc(C)cc3)c(C#N)cc2c1
