Show answer & explanation
Correct answer: B
Answer: Processing unit -> Arithmetic and Logic Unit (ALU); Instruction unit -> Timing and Control; Storage and Interface unit -> General-purpose Registers.
Processing unit: Contains the Arithmetic and Logic Unit (ALU) which performs arithmetic and logical operations required by instructions.
Instruction unit: Handles instruction fetch, decode, sequencing and generates control and timing signals, so it corresponds to the timing and control function.
Storage and Interface unit: Provides registers and interfaces to memory and I/O, so it corresponds to the general-purpose registers and storage elements.
Therefore the correct mapping is: Processing unit -> ALU; Instruction unit -> Timing and Control; Storage and Interface unit -> General-purpose Registers.
