To solve this question, we must first understand what each of our options mean.
Option 1 - Still Life
A still life portrait typically has objects in it. It can contain random things that go well together giving a pleasing look to the eye.
Option 2 - Landscape
A landscape portrait is usually a portrait of a place of nature or Earth. For example, if you painted a picture of Cradle Mountain including the lakes and sky, this would be known as a landscape portrait.
Option 3 - Genre
A genre portrait is kind of like a half body portrait. Most often the person is sitting down and striking a plain natural pose.
Option 4 - Self-Portrait
A self-portrait can be described as a headshot painting. It is a painting focused on the face. This painting can sometimes show the neck or chest area of the individual but most often no more than that.
Now that we know a pretty good description of what each of our options means, we can use the elimination process to remove our options one by one.
First off, a self-portrait, being a portrait of one's self, is not related to the picture we are provided so we know that is not the answer.
Now a genre portrait, being similar to a self-portrait, is also not the answer because our image has no human in the background or setting.
A landscape can also not be our answer because our image shows no scenery of any kind.
This leaves only one option which is the still portrait. The definition matches with the image so we know this is correct.
SHORT ANSWER:
This artwork is an example of a still life portrait.
