Task: Answer the MCQ question.
Question: Which compound has a -20.822% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) CC(C)C[C@@H]1NC(=O)[C@H](CO)NC(=O)c2cc([N+](=O)[O-])cc(I)c2OCC[C@@H](C(N)=O)NC1=O
b.) N#Cc1c(N)sc2c1CCN(CCc1ccccc1)C2
c.) O=C(NCc1cccnc1)c1ccc(-c2cccc([N+](=O)[O-])c2)o1
d.) O=[N+]([O-])c1ccc(-c2nc(-c3cccs3)c(-c3cccs3)[nH]2)cc1
