Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 0.858\% 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] CCn1cc(/C=N/N=C2\CCC3C4CCc5cc(O)ccc5C4CC[C@]23C)c(C)n1
[b] CC1=NN(C(C#N)c2cccc([N+](=O)[O-])c2)C(C)(C)C1
Answer: a. CCn1cc(/C=N/N=C2\CCC3C4CCc5cc(O)ccc5C4CC[C@]23C)c(C)n1
