Answer:
C. High pressure.
Step-by-step explanation:
The meteorological condition most typically associated with a heat wave is high pressure. A heat wave is a period of unusually hot and dry weather that can last for several days or weeks, and it is often accompanied by high levels of humidity and the absence of clouds.
High pressure is a meteorological condition that is characterized by the presence of a high-pressure system, which is an area of relatively calm and stable weather. High-pressure systems are typically associated with clear skies, light winds, and dry conditions, and they can cause the temperature to rise above normal levels, leading to heat waves.
