Concept:
A palette is a graphical user interface element commonly found in design, graphics, and image-editing software. It provides easy access to tools and commands required by the user.
Step 1: Understand what a palette does in software applications.
A palette generally contains frequently used items such as:
• Drawing tools
• Color selections
• Brushes
• Shapes
• Editing commands
These options help users work efficiently.
Step 2: Observe how palettes appear on the screen.
Unlike a menu bar fixed at the top of the screen, a palette usually appears as a movable floating window.
Users can drag it to different positions while working.
Step 3: Compare with the given options.
Option (B) correctly describes a palette as:
\[
\text{A small floating window containing tools and colors}
\]
The remaining options refer to other interface components.
Step 4: Select the correct answer.
Hence,
\[
\boxed{\text{Option (B)}}
\]
is the correct answer.
