I failed the emission test due to OBDII Monitors Not Ready. Does anyone have an idea for that?

Vehicles have different "monitors" or computer tests that are run within the software of the vehicles "computer" called the engine control module. These test look at different parameters from sensors on the engine and sometimes transmission during manufacturer defined driving conditions. These tests can either pass, fail, or be incomplete. Usually driving the vehicle within these parameters will cause the tests to either pass or fail. If they pass you are good to go for your inspection if they fail a check engine light is illuminated and code stored in the engine control module and you can read the code and from there diagnose the problem.
