B. a thunder storm. creates dangerous lightning and hail

b. a thunderstorm

Explanation:

A thunderstorm is also knowns as the electric storm or lightning storm that is characterized by lightning and relatively thunderstorms are called thundershowers. These are usually accompanied by heavy rains and strong winds. These thunders tom may line up and may create a rainband. They also result in the rapid development of warm and moist air and hence led to the formation of fronts. Mostly all thunderstorms produce hail effects and are due to when the updrafts can no longer support the weight of ice. The stronger the drafts the larger is the hail.

So  if  the sum of the enthalpies of the reactants is greater than the products, the  reaction  will be  exothermic.  if  the products side has a larger enthalpy, the  reaction  is  endothermic. you may wonder why  endothermic reactions, which soak up energy or enthalpy from the environment, even happen
