Final answer:
Drawing is not always expensive and time-consuming.
Step-by-step explanation:
The answer that is not true is option d. Drawing is expensive and takes a long time to produce. Drawing can be done with various materials such as silverpoint, pencil, charcoal, pastel, crayon, and chalk, as mentioned in option b. Drawings can be considered works of art in their own right, or they can be preparatory sketches for larger projects, as stated in option c. However, option d is incorrect as drawing does not have to be expensive nor does it always take a long time to produce. It can be done quickly and with minimal cost depending on the desired outcome and the artist's technique.
