Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 3.084\% 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 other words.
Options:
a) CN(c1cccc(NC(=O)Nc2cccc(Cl)c2)c1)S(C)(=O)=O
b) Cc1ccc2nc(N3CCN(S(=O)(=O)c4ccc5c(c4)OCCO5)CC3)c(C#N)cc2c1
Answer: a. CN(c1cccc(NC(=O)Nc2cccc(Cl)c2)c1)S(C)(=O)=O
