Task: Answer the multiple choice question.
Question: Which compound exhibits a 18.476\% 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.) C[C@@H]1C(=O)O[C@@H]2[C@H](O)C34[C@@H]5OC(=O)C3(O[C@H]3OC(=O)[C@H](O)C34[C@H](C(C)(C)C)[C@H]5O)[C@@]12O
b.) O=C(c1ccc(N2CC3CC(C2)c2cccc(=O)n2C3)c([N+](=O)[O-])c1)N1CCCC1
Answer: a. C[C@@H]1C(=O)O[C@@H]2[C@H](O)C34[C@@H]5OC(=O)C3(O[C@H]3OC(=O)[C@H](O)C34[C@H](C(C)(C)C)[C@H]5O)[C@@]12O
