Problem statement: Answer the multiple-choice question.
Question: Which drug has a 3.336\% 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 O=C1NC(c2ccccc2)=CC(c2ccccc2O)N1
b CC(C)c1oc(=O)cc2c1[C@@H](O)[C@H]1OC(=O)[C@@]3(C)CC[C@@H](O)[C@@]2(C)C13
Answer: a. O=C1NC(c2ccccc2)=CC(c2ccccc2O)N1
