Problem statement: Answer the multiple-choice question.
Query: Which drug has a 5.226\% 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=C(/C=C/c1ccccc1[N+](=O)[O-])N1CCCCC1
b.) O=C(OCc1nnc(-c2ccccc2)o1)c1cn(-c2ccccc2)nc1-c1ccccc1
Answer: a. O=C(/C=C/c1ccccc1[N+](=O)[O-])N1CCCCC1
