Task: Answer the multiple choice question.
Question: Which compound has a 3.840% 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 other words.
Options:
(a) COCCC1=NN(c2nc3ccccc3s2)C(O)(C(F)(F)F)C1
(b) O=C1CC(c2ccccc2)Sc2nc(-c3ccccc3)c(-c3ccccc3)n21
Answer: b. O=C1CC(c2ccccc2)Sc2nc(-c3ccccc3)c(-c3ccccc3)n21
