A) cone
B) cube
C) pyramid
D) sphere
Is it A or D?

Looks like B to me.
a cone and a pyramid have exactly one base.
a sphere has 0 bases, which is also 1 or less.
A cube has 6 faces, any of which could be called a base.
But the question asks which one does NOT have a base.
so the answer is D)
The answer is B because cubes have more than one base
To determine which option is correct, we need to understand the definition and properties of each shape mentioned. Let's go through them one by one:
A) Cone: A cone is a three-dimensional geometric shape with a circular base and a pointed top. It has one base, so it meets the condition mentioned in the question, "at most one base." Therefore, it can be a solid with at most one base.
B) Cube: A cube is a three-dimensional geometric shape with six square faces, and all edges are of equal length. It has six faces, which are essentially six bases. Therefore, it does not meet the condition mentioned in the question and, thus, cannot be a solid with at most one base.
C) Pyramid: A pyramid is a three-dimensional geometric shape with a polygonal base and triangular faces converging to a single vertex called the apex. It has one polygonal base and multiple triangular faces, which essentially act as additional bases. Therefore, it does not meet the condition mentioned in the question and cannot be a solid with at most one base.
D) Sphere: A sphere is a perfectly symmetrical three-dimensional geometric shape that resembles a ball. It does not have any bases as it does not have any flat faces. Therefore, it meets the condition mentioned in the question, "at most one base." Hence, it can be a solid with at most one base.
Based on our analysis, we can conclude that the solid in question must be option B) cube since it has multiple bases, unlike the cone and sphere.
