Task: Answer the multiple-choice question.
Query: Which drug has a 10.840\% 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(Nc1cc(C(F)(F)F)ccc1N1CCCC1)C1CCCO1
(b) COCC(=O)Nc1ccc([N+](=O)[O-])cc1OC
Answer: a. O=C(Nc1cc(C(F)(F)F)ccc1N1CCCC1)C1CCCO1
