Arithmetic Operations are performed by:

A) LU
B) AU
C) ALU
D) CU

🧠 Explanation:

Arithmetic operations in a computer are performed by the Arithmetic Logic Unit (ALU), a core CPU component. The ALU handles calculations like addition, subtraction, multiplication, and division, as well as logical operations like comparisons. It processes data in binary, enabling fast, accurate computations for tasks from basic math to complex algorithms. Understanding the ALU’s role is essential in computer architecture, as it drives processing power in devices like computers and smartphones. Its efficiency impacts performance in fields like engineering, gaming, and data analysis, making it a cornerstone of modern computing systems and technology.
