Task: Answer the multiple choice question.
Question: Which compound has a 18.782% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=c1sc(/C=N/Nc2ccccc2)c(Cl)n1Cc1ccccc1
b O=C(COC(=O)CNC(=O)c1ccccc1)Nc1cccc(Br)c1
Answer: a. O=c1sc(/C=N/Nc2ccccc2)c(Cl)n1Cc1ccccc1
