According to Henry Ford: Select one: a. Power and machinery, money and goods, are useful only as they set us free to live. b. Power and machinery, money and goods, are not only useful, but necessary. c. Power and machinery, money and goods, are unfortunate additions to entrepreneurship. d. Power and machinery, money and goods always set us free to live.

The correct answer is letter "A": Power and machinery, money and goods, are useful only as they set us free to live.

Explanation:

American entrepreneur Henry Ford (1863-1947) was the author of the transportation and industry revolution in the U.S. He obtained around 160 patents registered in America. The "Fordism" was named after him because of his method of producing large quantities of automobiles at low cost through mass production.  

According to Ford: "Power and machinery, money and goods, are useful only as they set us free to live. They are but means to an end. For instance, I do not consider the machines which bear my name simply as machines. If that was all there was to it I would do something else." ("My Life and Work", 1922).
