What can be inferred from the term "Continuous lightning"?

The term "Continuous lightning" indicates that there is consistent and ongoing lightning activity occurring in a specific area. This descriptor suggests that the lightning is not sporadic or occasional but rather sustained over a period of time. This could be associated with a thunderstorm or similar weather phenomena where electrical discharges are frequent and persistent.

The other options do not relate to the meaning of "Continuous lightning." For instance, intermittent thunder with sporadic rain would imply variability, which contradicts the notion of continuity. No significant weather events suggest calm conditions, while heavy snowfall refers to a different type of weather phenomenon altogether. Hence, the choice that aligns with the definition of "Continuous lightning" is that it refers to consistent and ongoing lightning activity.
