• A. John Standard
• B. Albert Gray
• C. Sarah Boone
• D. James "Patch" Talley

Answer: (A)

John Standard is credited with inventing a version of the refrigerator in 1891. His innovation improved the ways in which food could be preserved by using a method of cooling that was more efficient compared to previous technologies. Standard's design featured a more practical approach to refrigeration, helping to pave the way for modern refrigeration systems we rely on today. His work contributed significantly to the food preservation industry and had a lasting impact on household and industrial refrigeration.

The other individuals listed, while notable in their own right, were not associated with the invention of the refrigerator. For instance, Albert Gray is not recognized for contributions to refrigeration, and Sarah Boone is celebrated for her work in improving the ironing board design. James "Patch" Talley is primarily known for his contributions to the field of sewing machines, not refrigeration. Recognizing the historical contributions of Standard helps to underscore the important role African American inventors have played in technological advancements.
