"c. A narrative source" is what a historian would use to get a firsthand account of a past event, since in these sources (which are also primary sources) a person is giving a first-hand account of the event itself.
Spain spent much of the 1920s under the dictatorship of Miguel Primo de Rivera, and the economic hardships caused by the Great Depression intensified polarization within the Spanish public.

Fascist and extreme-right forces responded in July 1936 with an army mutiny and coup attempt that expanded into a civil war.
