Problem statement: Answer the multiple choice question.
Query: Which drug has a 1.747\% 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=C1/C(=C/c2cccnc2)CCc2c1[nH]c1ccccc21
b COc1cc(/C=C/[N+](=O)[O-])ccc1O
Answer: a. O=C1/C(=C/c2cccnc2)CCc2c1[nH]c1ccccc21
