Best Answer Explained in Below-:

The term 'cartographer' specifically refers to an individual who specializes in the creation and design of maps. Cartographers employ techniques from various disciplines, including geography, art, and science, to accurately represent spatial information. They focus on elements such as scale, symbols, and color to convey geographical features effectively, making maps both informative and easy to understand.

In contrast, the other options provided do not align with the act of mapping. A painter primarily creates visual artwork, a sculptor carves or molds three-dimensional works from various materials, and a geologist studies the Earth’s physical structure and substance. While a geologist may utilize maps in their work, they are not the ones who create them.

Thus, in the context of the question, 'One who draws a map is_________', the correct answer is unequivocally 'D) Cartographer'. This designation accurately describes the profession dedicated to the art and science of map-making.
