Which of the following is responsible for executing instructions in a computer system?

• A. Hard drive
• B. Motherboard
• C. Central Processing Unit
• D. Random Access Memory

Answer: (C)

The Central Processing Unit (CPU) is responsible for executing instructions in a computer system. It acts as the main processing unit that performs calculations, runs applications, and manages data flow between the computer's components. The CPU interprets and executes instructions from both system software and application software, facilitating the overall operations of the computer. The hard drive serves as a storage device that retains data and programs, but it does not execute instructions. While the motherboard connects all components of the computer and allows communication between them, it does not perform processing tasks itself. Random Access Memory (RAM) temporarily stores data and instructions that the CPU needs to access quickly, but it also does not execute those instructions. Therefore, the CPU is uniquely suited for the function of executing instructions, making it the correct answer to the question.
