Task: Answer the multiple choice question.
Question: Which drug exhibits a -3.530% 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) CCCc1c(C)nc(N2CCN(c3ccccc3F)CC2)[nH]c1=O
b) CS(=O)(=O)N1CCN(c2c(Cl)cccc2[N+](=O)[O-])CC1
Answer: b. CS(=O)(=O)N1CCN(c2c(Cl)cccc2[N+](=O)[O-])CC1
