Cornelius Vanderbilt. He was a great during and after the Industrial Revolution. He made a great amount of money with his railroads.
Andrew Carnegie- he was known for his steel works.
Though for whoever made this question it would have good to make one of the answer choices Rockefeller another great during those times. For he was known to work with Vanderbilt at one time. 
The other choices I have no voice on them.
        
             
        
        
        
The appropriate rider allows premium payments to be waived in the event of disability. There is usually a waiting period of 3 or 6 months once the policy owner becomes disabled before the first premium will be waived.
Long-term disability insurance plans are made to pay benefits for a longer time. The premiums are normally greater the longer the benefit term. This is why insurance companies offer optional clauses so you can customise your coverage to meet your needs. Benefit for Basic Partial Disability, If you sustain a disease or injury that affects your capacity to work but does not result in total disability, this offers partial payments. Benefit for Enhanced Partial Disability, For fee-for-service professionals and business owners, this specific Guardian rider may be especially useful. It offers benefits when you experience an income loss of 15% or more simply as a result of illness or injury.
