Solution
The correct options are
A Point
B Plane
C Line
There are three words in geometry that are not formally defined, which are point, line, and plane. These are referred to as "three undefined terms of geometry".
Point has no dimension, no size, no breadth, no height, and no width, it exists by itself.
A line has no thickness, extends in one dimension and goes on forever in both directions.
A plane has two dimensions, forms a flat surface extending indefinitely in all directions and has infinite length, infinite width and zero height (thickness).
While in geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex.
