First,, let's count how many vertexes our figure has. To find this out,, we need to count how many corners the figure has. On the bottom of the figure we have 4 vertexes,, and on the top we have 1 vertex which means we have 5 total vertexes. Now lets count how many faces our figure has. Since it is a 3D shape,, we have one face on the bottom and 4 faces around the triangle. This tells us that we have 5 faces. Finally,, we can count the edges by looking at lines of our triangle. Edges are the long corner lines that lead to the tip of the triangle,, which means that we have only 4 edges. This means that we have 5 faces,, 5 vertices,, and 4 edges making the correct answer option C.
Let me know if you have any further questions.
