Task: Answer the multiple choice question.
Query: Which compound has a -10.526\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(c1ccc(-c2ccc([N+](=O)[O-])cc2)o1)N1CCCCC1
b) O=c1oc(-c2cccs2)nc2sc3c(c12)CCCCC3
Answer: a. O=C(c1ccc(-c2ccc([N+](=O)[O-])cc2)o1)N1CCCCC1
