Task: Answer the MCQ question.
Query: Which drug has a 2.441\% 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 O=C(COC(=O)COc1ccc(Br)cc1)NCc1ccccc1
b CCOC(=O)/C(C(N)=NCCO)=C(/O)c1ccccc1
Answer: a. O=C(COC(=O)COc1ccc(Br)cc1)NCc1ccccc1
