Correct option is B
When selecting the size of a drawing sheet, the most important factor is clarity and readability of the drawing. The sheet must be large enough to accommodate all views, dimensions, and details without overcrowding. If the sheet is too small, important details may be unclear; if too large, space is wasted. Therefore, clarity and resolution take priority over other factors. Orientation (horizontal/vertical) and standard sizes are secondary considerations. The primary goal of engineering drawing is effective communication, which depends on clear representation.
