The CPU (Central Processing Unit) is the main component responsible for processing data and executing instructions in a computer. Therefore, Option A (CPU) is the correct answer.
The CPU performs arithmetic, logical, control, and other operations required to execute computer programs. It receives instructions and data, processes them according to the instructions, and produces the required results.
The CPU is commonly described as the "brain of the computer" because it controls and coordinates many of the computer's operations. It consists of important components such as the Arithmetic Logic Unit (ALU), Control Unit (CU), and registers.
RAM (Random Access Memory) temporarily stores data and instructions that the CPU is currently using, but it does not itself serve as the primary processing unit. VDU (Visual Display Unit) refers to a display device used to show information to the user. DCU is not the standard answer for the computer's main data-processing component.
CPU → Processing ✅
RAM → Temporary Storage
VDU → Display/Output
