Task: Answer the multiple choice question.
Question: Which drug exhibits a -8.109% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a CCOC(=O)c1cc(C#N)c(SCC(=O)c2cc(C#N)c(SC)nc2C)nc1C
b CS(=O)(=O)N1CCN(c2ccc([N+](=O)[O-])c(NCc3ccccc3)c2)CC1
Answer: b. CS(=O)(=O)N1CCN(c2ccc([N+](=O)[O-])c(NCc3ccccc3)c2)CC1
