Task: Answer the MCQ question.
Query: Which compound has a 20.452% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a Cc1ccccc1Nc1nc(N)nc(COC(=O)c2cccc(S(=O)(=O)N(C)c3ccccc3)c2)n1
b Cc1ccccc1N/C(SCc1cccc(Br)c1)=C(/C#N)C(N)=O
Answer: b. Cc1ccccc1N/C(SCc1cccc(Br)c1)=C(/C#N)C(N)=O
