E Correct answer
Explanation

The CPU (Central Processing Unit) is the primary component responsible for processing data. It fetches instructions and data from memory, performs arithmetic and logical operations on them, and stores the results back. This input-processing-output cycle is the fundamental operation of computing. Peripherals provide input/output, memory stores data, but the CPU does the transformation.
