Final answer:
Abraham Lincoln, not included in the provided choices, was the president most notably mocked for his unkempt appearance by the press.
Step-by-step explanation:
The president who was often mocked in the press for his unkempt appearance was Abraham Lincoln. While not one of the options provided, Lincoln was known for his tall, lanky frame, sometimes unruly hair, and a generally less polished appearance compared to other politicians of his era. This portrayal was often exaggerated by cartoonists and in the press during his time in office. None of the provided options, Andrew Johnson, Ulysses S. Grant, Rutherford B. Hayes, or Chester A. Arthur, were particularly noted for being mocked for their appearance to the extent that Lincoln was.
