Task: Answer the multiple choice question.
Question: Which drug has a 2.857% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=C(c1ccccc1)[C@H]1[C@H](c2ccccc2)[C@@]2(N=C(c3ccccc3)OC2=O)C2c3ccccc3C=NN21
[b] CCn1c(NCCc2ccc(OC)c(OC)c2)nc2c1c(=O)n(C)c(=O)n2C
Answer: a. O=C(c1ccccc1)[C@H]1[C@H](c2ccccc2)[C@@]2(N=C(c3ccccc3)OC2=O)C2c3ccccc3C=NN21
