Hey there!
Your answer is D, Hector P. Garcia.
In 1984, president Ronald Reagon presented Garcia with the Presidential Medal of Freedom. He founded the American GI Forum, was a World War 2 veteran, and on top of all this, was even a medical surgeon. He made many medical contributions to society and served our country. He was truly a man who dedicated his life to the well-being of others.
Hope this helps, and be sure to come to me with any other questions!
