The correct answer will be B, while people are naturally made, our habits are not considered natural.
Early short films that focused on everyday life and did not assume a narrative format were called actualities.
Actualities were non-fiction films, usually no longer than 1-2 minutes, featuring raw, unstructured images of real-life events, places, people, or things. Documentary film's predecessor, actualities, was a popular form of entertainment from the early 1890s until about 1908.
In fact, actualities predated the emergence of documentary cinema. They were compiled into programs by exhibitors – as popular and prominent as their fictional counterparts. It wasn't as clear as it was after it was in formal form. Alongside the travel reality genre, actualities is a film genre strongly associated with still images.
Around 1908, despite the declining topicality of the film genre, there is still talk of the actualities as a component of documentary filmmaking.
