Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.554\% hERG inhibition at 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)/C=C/c1ccc(Br)o1)Nc1ccc2[nH]c(=O)[nH]c2c1
b) O=C1CN(C(=O)COc2ccc(F)cc2Br)c2ccccc2N1
Answer: a. O=C(COC(=O)/C=C/c1ccc(Br)o1)Nc1ccc2[nH]c(=O)[nH]c2c1
