Task: Answer the multiple choice question.
Question: Which drug has a -1.698\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a COc1ccccc1/C=C/C(=O)Nc1ccc2c(c1)CCC2
b O=c1[nH]c(/C=C/c2ccccc2)c([N+](=O)[O-])c(=O)[nH]1
Answer: a. COc1ccccc1/C=C/C(=O)Nc1ccc2c(c1)CCC2
