What can be called an open shape?
Answer and explanation
Correct answer: One whose boundary is incomplete somewhere
An open shape is an outline that does not join completely. It has a gap or an unfinished part, so its boundary does not fully enclose an inside region. The opening may be small or large, but the essential feature is that the line is not connected all the way around. Colour, the number of sides, and the particular object do not decide whether a shape is open.
Option A is correct because an incomplete boundary is the defining feature of an open shape. Option B refers only to colour and is not necessary. Option C describes a possible square-like form, not openness. Option D is also too narrow, since a circle is normally closed and is not the only possible shape. Thus, an unfinished boundary identifies an open shape.
