Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 15.358\% 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) CO/N=C/C(C#N)=C/c1ccc(OC)cc1
(b) CC(C)(C)NC(=O)COC(=O)c1cc(Br)ccc1Cl
Answer: a. CO/N=C/C(C#N)=C/c1ccc(OC)cc1
