Explanation:
The correct answer is: A. input → process → output

- This is the standard and logical sequence in data processing:

Input – Data is collected and entered into the system (e.g., typing numbers into a spreadsheet).

Process – The system processes the data using instructions or calculations (e.g., totaling, sorting, analyzing).

Output – The result of the processing is presented (e.g., a report, chart, or printed result).

This cycle is fundamental in both manual and computerized data systems.



Why not the other options?
B. input → output → process – Output cannot occur before processing.

C. process → input → output – Processing can’t begin without data input.

D. process → output → input – Incorrect sequence; breaks the logical flow of data handling.
