Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 2.258\% 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. COC(=O)N/N=C\c1c(C)nn(-c2ccccc2)c1Cl
b. C/C(=N\Nc1ccc(C#N)cc1[N+](=O)[O-])c1ccc(O)cc1
Answer: a. COC(=O)N/N=C\c1c(C)nn(-c2ccccc2)c1Cl
