Task: Answer the multiple choice question.
Query: Which compound exhibits a -3.526% human ether-à-go-go related gene (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 additional words.
Options:
a: CC(=O)Nc1cccc(NC=C(C#N)C#N)c1
b: CNC(=O)c1ccc(Nc2nnc(-c3ccc(O)cc3)c3ccccc23)cc1
c: CC(=O)Nc1cc(-c2nn(CC(=O)N3CCCCC3)c(=O)c3ccccc23)ccc1N1CCOCC1
d: CC(=O)c1ccc(O)c(CO)c1
Answer: d. CC(=O)c1ccc(O)c(CO)c1
