Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -2.973\% 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 or b without using any additional words.
Options:
a: C/C(=N/NC(=O)CNC(=O)CCc1ccccc1)c1ccc(Cl)c(Cl)c1
b: COc1ccc(-c2nn(-c3ccccc3)cc2C#N)cc1
Answer: b. COc1ccc(-c2nn(-c3ccccc3)cc2C#N)cc1
