What are Instrument Meteorological Conditions (IMC) parameters?

Explanation:
IMC means weather conditions that require flying by instruments rather than outside visual references. The standard threshold used to define IMC is ceilings below 1,000 feet or visibility below 3 statute miles. If either condition is met, visual cues are unreliable, so pilots operate under instrument flight rules. The other options describe conditions that allow visual flight: ceilings at or above 1,000 feet with visibility at least 3 miles, clear weather with unlimited visibility, or higher ceilings and visibility.
