D) Sketch

A sketch is a rough drawing that represents the main features of an area without using any scale. It is a simple and quick way to visually depict an area and is often used for preliminary planning or to convey ideas in a visual form. Here is a detailed explanation of why a sketch is the correct answer for a rough drawing showing only some features of an area drawn without using any scale.

Definition of a Sketch
A sketch is a freehand drawing that is done quickly and without much detail. It is a simplified representation of an object or area, capturing only the essential features. Unlike a scale drawing or a map, a sketch does not adhere to any specific measurements or proportions. It is meant to be a quick and rough representation, often used as a starting point for more detailed drawings or plans.

No Scale
One of the key characteristics of a sketch is that it does not use any scale. In a scale drawing or map, measurements are accurately represented to scale, allowing for precise measurements and calculations. However, in a sketch, the focus is on capturing the overall impression or essence of the area, rather than its precise measurements. This lack of scale allows for a more free and expressive representation of the features.

Main Features
A sketch typically focuses on capturing the main features of an area. Instead of including every detail, a sketch highlights the essential elements that define the area. For example, if drawing a sketch of a park, the sketch may include the outline of the park, the location of major trees or landmarks, and perhaps a few people or animals to bring the scene to life. The goal is to convey the main features of the area in a simple and concise manner.

Quick and Simple
Sketches are meant to be quick and simple drawings. They are often done rapidly and without much planning, allowing for a spontaneous and creative representation of the area. Unlike a map or a scale drawing, which require careful measurements and calculations, a sketch can be done on the spot, capturing the immediate impression of the area. This simplicity and spontaneity make sketches a valuable tool for brainstorming, exploring ideas, and communicating concepts visually.

Conclusion
In conclusion, a sketch is a rough drawing that represents the main features of an area without using any scale. It is a quick, simple, and expressive way to visually depict an area, focusing on the essential elements rather than precise measurements. Sketches are valuable tools for brainstorming, planning, and communicating ideas visually.
