Task: Answer the multiple choice question.
Query: Which drug has a 4.561\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCCCCCC(Cl)(Cn1ccnc1)c1ccccc1.O=[N+]([O-])O
(b) O=C(Nc1ccc2c(c1)OCO2)C1CC(c2ccccc2Cl)=NO1
Answer: b. O=C(Nc1ccc2c(c1)OCO2)C1CC(c2ccccc2Cl)=NO1
