Task: Answer the MCQ question.
Question: Which drug has a -2.989% 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=C1NN(c2ccccc2)C(=O)/C1=C\c1coc2ccc(O)cc2c1=O
b O=C(COC(=O)c1ccccc1Br)Nc1ccc2[nH]c(=O)[nH]c2c1
Answer: b. O=C(COC(=O)c1ccccc1Br)Nc1ccc2[nH]c(=O)[nH]c2c1
