Well Primary Succession means you are the first organisms of that area after it is destroyed completely or if it's new. Secondary Succession is when an area is not destroyed completely but the organisms that remain colonize the area again. I believe it's C.

C. Primary succession

An ecological succession is a change that occurs in the biotic community of an ecosystem due to changes that occur in non-living factors (weather, climatic conditions, sunlight, water, soil, temperature and disaster or calamity) and time, until the ecosystem attains stability. A primary succession occurs in a region, which was previously colonized by living species but destroyed by a disaster like retreating glacier or volcanic eruption. The region is completely barren and exhibit no life form.

Therefore, the recolonization of an area that has been totally destroyed, is an example of primary succession.

explanation:

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
