Task: Answer the multiple-choice question.
Question: Which drug has a 8.026\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) C=CCn1c(O)c(C(C)=Nc2cc(OC)ccc2OC)c(=O)[nH]c1=O
(b) CCN(CC)CCOCCOc1ccc(Cl)c2ccccc12
Answer: a. C=CCn1c(O)c(C(C)=Nc2cc(OC)ccc2OC)c(=O)[nH]c1=O
