Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 10.976\% 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. CCn1nc([N+](=O)[O-])c(C(C#N)c2nc3ccccc3n2C)c(Cl)c1=O
b. COc1ccc(N=C2C(=Nc3ccc(OC)cc3)N(c3ccccc3)C(=S)N2C(=O)c2ccc(Cl)cc2)cc1
Answer: a. CCn1nc([N+](=O)[O-])c(C(C#N)c2nc3ccccc3n2C)c(Cl)c1=O
