Which form has a fully curved surface?
Answer and explanation
Correct answer: Sphere
A sphere is a solid form whose surface curves continuously in every direction around its centre. It has no flat face, straight edge, or corner, so option A is correct. A cube is made of six flat square faces and has straight edges and vertices. A rectangle and a square are two-dimensional plane shapes with straight sides; they do not represent a fully curved solid surface. In drawing and sculpture, a sphere is often used to practise gradual shading because its rounded surface changes smoothly from highlight to mid-tone and shadow. Recognising the absence of corners and flat faces is a reliable way to distinguish a sphere from the other choices.
