Correct option is A. John Von Neumann
The von Neumann architecture, also known as the von Neumann model, is the foundation of modern computer design. It was proposed by the mathematician and physicist John von Neumann in the 1940s. This architecture is characterized by the use of a central processing unit (CPU) that can execute a series of instructions stored in memory. The instructions are fetched from memory, decoded, and executed sequentially, allowing for the manipulation of data and the execution of various operations. This concept of stored-program computers revolutionized the field of computing and forms the basis for virtually all modern computers today.
