Task: Answer the MCQ question.
Query: Which compound has a -20.638% 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, or c without using any other words.
Options:
[a] O=C1C2C3C=CC(CC3)C2C(=O)N1c1ccccc1
[b] Cc1ccccc1-c1nc2cc(N)ccc2o1
[c] Cc1cc2c(c(=O)n1C1CC1)C(c1cccc(Cl)c1)C(C#N)=C(N)O2
Answer: c. Cc1cc2c(c(=O)n1C1CC1)C(c1cccc(Cl)c1)C(C#N)=C(N)O2
