Problem statement: Answer the multiple choice question.
Question: Which compound has a 5.409\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=S(=O)(c1ccccc1)N1N=C(c2ccccc2)CC1c1ccccc1
b. O=c1cc(-c2ccc([N+](=O)[O-])cc2)c2cc3c(cc2[nH]1)OCCO3
Answer: a. O=S(=O)(c1ccccc1)N1N=C(c2ccccc2)CC1c1ccccc1
