Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.332\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CN1C(N)=NC(=O)/C1=C/c1ccccc1F
b COc1cc(C)nc(OCCNC(=O)COc2ccc(Cl)cc2C)n1
Answer: a. CN1C(N)=NC(=O)/C1=C/c1ccccc1F
