Task: Answer the multiple choice question.
Query: Which compound has a -44.970\% 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 other words.
Options:
a O=c1ccc(-c2nc3cc(Cl)ccc3n2Cc2ccccc2)c[nH]1
b c1ccc(C2=Nc3ccccc3OC2)cc1
Answer: a. O=c1ccc(-c2nc3cc(Cl)ccc3n2Cc2ccccc2)c[nH]1
