Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 12.870% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CC1(C)N([O-])C(c2ccccc2)=C[N+](=O)C1(C)C
[b] CCN1C(=O)N[C@@H](c2ccccc2)[C@H](C(C)=O)[C@H]1C
Answer: b. CCN1C(=O)N[C@@H](c2ccccc2)[C@H](C(C)=O)[C@H]1C
