One of the most important characteristics of OSPF is Multiple areas. Which statement best describes why this feature is such an important enhancement to earlier routing protocols?() A. The network domain, when divided into areas, allows for the use of both IANA classful addressing and private addressing.B. The use of multiple areas allows for the use of prioritization.C. All computation is kept within the area, with minimum communication between the areas,allowing the network to scale to larger sizes.D. It is easier to implement security.
