Task: Answer the MCQ question.
Question: Which drug exhibits a 12.028\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: Cc1ccc(C2C(C#N)=C(N)N(c3cccnc3)C3=C2C(=O)CCC3)s1
b: O=C(Nc1ccc(S(=O)(=O)N2CCN(c3ccccc3)CC2)cc1)c1cccs1
Answer: a. Cc1ccc(C2C(C#N)=C(N)N(c3cccnc3)C3=C2C(=O)CCC3)s1
