Which word implies an obvious truth?

The word "overt" means something that is open and observable, easily recognized or understood, and does not require interpretation or hidden meaning. It implies clarity and directness, indicating that the truth is manifestly apparent. In contrast, terms like "ambiguous" refer to something that can be understood in more than one way, "subtle" suggests something that might be difficult to perceive or grasp without careful thought, and "hidden" clearly indicates something that is concealed or not immediately visible. The choice of "overt" as the correct answer highlights its association with transparency and evident truths.
