Task: Answer the multiple choice question.
Query: Which drug has a 0.519% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C1C(c2ccncc2)=C(O)c2ccccc21
b) CCCCOC(=S)NC(=O)c1sc2ccccc2c1Cl
Answer: b. CCCCOC(=S)NC(=O)c1sc2ccccc2c1Cl
