Answer: (C)

A successful enterprise architecture is fundamentally built on several key components, which include business architecture, information architecture, applications architecture, and technology architecture. Each of these elements plays a vital role in ensuring that an organization's IT strategy aligns with its business goals.

Business architecture defines the structure of the organization by outlining the business processes, organizational structure, and governance frameworks. This component is crucial because it helps establish the context within which the technology operates and allows for alignment between strategic objectives and IT capabilities.

Information architecture focuses on how data is managed and utilized across the organization. This includes data modeling, data storage, and access strategies, which ensure that the necessary information is available to support business processes effectively.

Applications architecture refers to the individual software applications that the organization uses to support its business operations. This component encompasses both the design and integration of applications, ensuring that they work together smoothly and meet the needs of the business.

Technology architecture encompasses the hardware and infrastructure necessary to support both applications and data. This includes servers, networks, and other technologies that allow the organization to operate efficiently and securely.

By integrating these four components, an enterprise architecture can provide a comprehensive framework that not only addresses current operational needs but also accommodates future growth and change. This holistic approach is key to enabling organizations
