The correct answer is A. SPARC.
SPARC (Scalable Processor Architecture) is a RISC (Reduced Instruction Set Computing) instruction set architecture developed by Sun Microsystems in the early 1980s. SPARC processors are used in a wide variety of applications, including servers, workstations, supercomputers, and embedded systems.
The 80386 is a 32-bit microprocessor developed by Intel in 1985. It is the successor to the 80286 and the first microprocessor in the 80386 family. The 80386 is a CISC (Complex Instruction Set Computing) processor.
The MC68030 is a 32-bit microprocessor developed by Motorola in 1987. It is the successor to the MC68020 and the first microprocessor in the MC68030 family. The MC68030 is a CISC processor.
The MC68020 is a 32-bit microprocessor developed by Motorola in 1984. It is the successor to the MC68010 and the first microprocessor in the MC68020 family. The MC68020 is a CISC processor.
RISC processors are designed to be simple and efficient, with a small number of instructions that can be executed quickly. CISC processors are designed to be more complex and flexible, with a larger number of instructions that can be used to perform a variety of tasks.
