Task: Answer the multiple choice question.
Question: Which drug has a 15.395\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COCCCNC(=O)CCCC(=O)NCCCOC
b: O=C(CNC(=O)c1ccc(Br)o1)NCc1cccc(Cl)c1
Answer: b. O=C(CNC(=O)c1ccc(Br)o1)NCc1cccc(Cl)c1
