Task: Answer the MCQ question.
Query: Which compound exhibits a 18.150\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CN(C)C(/C=C/Nc1ccc(O)cc1)=C(C#N)C#N
b: CC(=O)Nc1cccc(-c2nnc(-c3ccccc3)o2)c1
c: O=C(COc1cccc(Cl)c1)Nc1cc(S(=O)(=O)N2CCOCC2)ccc1N1CCOCC1
Answer: a. CN(C)C(/C=C/Nc1ccc(O)cc1)=C(C#N)C#N
