Task: Answer the MCQ question.
Question: Which drug has a -0.169% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: Cl.N=C(N)SCc1ccc(O)c([N+](=O)[O-])c1
b: CN(c1ccccc1C(=O)N1CCN(c2ccccc2)CC1)S(C)(=O)=O
Answer: a. Cl.N=C(N)SCc1ccc(O)c([N+](=O)[O-])c1
