Which of the following is an example of an extended definition?

A.) Automated systems are the cause of the loss of many jobs. Experts say that industrial automation will only grow with the increase of technology - especially due to the growth of the Internet and wireless capabilities. Systems can be customized for almost any segment of manufacturing or servicing.
B.) The rise of automated systems has also cost workers jobs. Automated systems use machines to perform tasks once done by humans. Unlike industrial robots that weld, paint, or assemble products, automated systems do not have specific tasks. Instead, they allow humans to conduct business transactions unassisted.
C.) Automated systems, or the use of machines to do human jobs, involves implementing automatic procedures in manufacturing or servicing.
D.) The International Society of Automation defines automated systems (noun) as "the creation and application of technology to monitor and control the production and delivery of products and services."
