• B. L.C. Bailey
• C. Jan Matzeliger
• D. Alexander Graham Bell

Answer: (A)

George Washington Carver is renowned for his innovative work with agricultural products, particularly in promoting alternatives to cotton during the early 20th century. He recognized the versatility of sweet potatoes and actively experimented with them in order to find new uses. Carver developed a variety of products from sweet potatoes, including flour and even a type of shoe polish. His efforts not only aimed to improve the livelihood of impoverished farmers but also demonstrated sustainable practices in agriculture, thereby contributing significantly to food science and commercial products derived from crops.

The other individuals mentioned, while influential in their respective fields, are not associated with sweet potatoes or the specific products listed. L.C. Bailey, for example, made contributions in different areas of invention, just as Jan Matzeliger is known for his innovation in shoemaking technology, and Alexander Graham Bell is primarily recognized for his work on the telephone.
