Task: Answer the multiple choice question.
Question: Which drug has a 19.497\% 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: CC(=O)O[C@H]1CC[C@@]2(C)[C@H](C1)C(=O)C[C@H]1[C@@H]3CC[C@@H]4[C@@H](CN5C[C@@H](C)CC[C@H]5[C@@]4(C)O)[C@@H]3C[C@@H]12
b: O=C1C=C(O)c2c(O)cc(O)c(O)c2C1=O
Answer: b. O=C1C=C(O)c2c(O)cc(O)c(O)c2C1=O
