Task: Answer the multiple choice question.
Query: Which drug exhibits a -6.272% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a C=CC[C@]12C=C(OC)C(=O)C=C1O[C@@H](c1ccc3c(c1)OCO3)[C@H]2C
b CCOc1ccccc1CNC(=O)c1cc2oc3ccccc3c2n1C
Answer: b. CCOc1ccccc1CNC(=O)c1cc2oc3ccccc3c2n1C
