What problem can occur from a very dark initial line while sketching?

Corrections may become difficult

The governing concept is the use of light construction lines during the first stage of a sketch. Early marks are provisional: the artist may need to change proportion, angle, position, or contour after comparing parts of the subject. If those first lines are extremely dark, they are harder to erase completely and may leave graphite, indentations, smudges, or confusing remnants beneath the corrected drawing. Therefore option A is correct. A dark beginning does not make a picture colourful, enlarge the paper, or cause the subject to disappear. A practical method is to use a light touch for placement and proportion, check the structure, then strengthen only the final contours and important details. This separates planning marks from finished lines and keeps the drawing clean and flexible.
