Task: Answer the multiple-choice question.
Question: Which drug exhibits a 11.950% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) COc1ccc(CCNC(=O)c2cc([N+](=O)[O-])cc([N+](=O)[O-])c2)cc1OC
(b) Cc1onc(-c2c(Cl)cccc2Cl)c1C(=O)N1CCN(c2ccccc2)CC1
Answer: a. COc1ccc(CCNC(=O)c2cc([N+](=O)[O-])cc([N+](=O)[O-])c2)cc1OC
