Problem statement: Answer the MCQ question.
Question: Which drug has a -3.224\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. CN(C)C(/C=C/Nc1ccc(Br)cc1)=C(C#N)C#N
b. O=C(O)CCc1ccc(-c2ccc(Cl)cc2)n1NC(=O)c1ccc(O)cc1
Answer: a. CN(C)C(/C=C/Nc1ccc(Br)cc1)=C(C#N)C#N
