Task: Answer the multiple-choice question.
Query: Which drug has a 13.155\% 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.) CC(=O)c1c(C(C)=O)c(C)n(NC(=O)c2ccccc2Cl)c1C
b.) O=C1N[C@@H](Cc2ccccc2)[C@@H](c2ccco2)O1
Answer: b. O=C1N[C@@H](Cc2ccccc2)[C@@H](c2ccco2)O1
