Step 1: Understanding the nature of painting
Painting, as a visual art form, is done on flat surfaces such as paper, canvas, or walls. These surfaces exist in the physical space having dimensions — length and breadth — and when combined with techniques like shading and perspective, they create an illusion of depth.
Step 2: Dimensions in art
Although the painting surface itself is two-dimensional, the composition and technique give it a visual three-dimensional effect. In common art terminology, painting is considered to represent the three dimensions: length, breadth, and an illusion of depth (perspective).
Step 3: Elimination
- Option (A) Four dimension — incorrect, as painting doesn't represent time or movement explicitly.
- Option (C) Two dimension — technically the medium is 2D, but not the representation.
- Option (D) None of these — invalid.

\boxed{\text{Three dimension is the most accurate answer.}}

Find the unknown frequency if 24 is the median of the following frequency distribution:
\[\begin{array}{|c|c|c|c|c|c|} \hline \text{Class-interval} & 0-10 & 10-20 & 20-30 & 30-40 & 40-50 \\ \hline \text{Frequency} & 5 & 25 & 25 & \text{$p$} & 7 \\ \hline \end{array}\]
Two concentric circles are of radii $8\ \text{cm}$ and $5\ \text{cm}$. Find the length of the chord of the larger circle which touches (is tangent to) the smaller circle.
