Answer:
The plane represented in the box is: fbcg
Explanation:
Given
The attached box
Required
Which of the given points is a plane in the box
To do this, we simply check if the points are connected i.e. if there is a directed between each of the points of the plane.
A. FBCG
Point F links to B, (by drawing a vertical line from F)
Point B links to C, (by drawing a right horizontal line from B to C)
Point C links to G, (by drawing a vertical line from C down to G)
Point G links to F, (by drawing a left horizontal line from G to F)
Hence, FBCG is a plane on the box.
This is not so for other options
