In terms of fine arts perspective is the art of representing three-dimensional objects on a two-dimensional surface so as to give the right impression of their height, width, depth, and position in relation to each other. if we look at the image shown here we can see that the image looks like it has been taking from front while standing a bit backwards from the pillars and corridor. Similarly the pillars on the back and the people have clear distance so option C is the correct answer.
The difference is when you draw by memory you won't remember every tiny detail, and you make/draw it in your own way vs. having the object in front of you you can copy it almost exactly.
