It is C or multi view since it is looking at the object from multiple sides as perspective
It is not assembly (A) since it is not showing how to put it together, it is not section(C) because it isn’t a chopped up piece of it and it is not exploded (D) because exploded is kinda like assembly where all components are separated and this picture isn’t so. It is C since it is simply showing the view from the top, side, and back
