Question

which storm is most likely to trigger forest fires due to lightning?
a cyclone
a hurricane
a thunderstorm
a tomado

Explanation:

Thunderstorms are known to produce lightning. Lightning can strike trees in forests, and if conditions are dry (e.g., dry leaves, dry wood), it can ignite a fire. Cyclones, hurricanes, and tornadoes are more associated with strong winds, heavy rainfall (in the case of cyclones and hurricanes), and the rotation of air masses (tornadoes). While they may have some electrical activity, thunderstorms are specifically characterized by frequent lightning which is a major cause of forest fires.

Answer:

a thunderstorm
