Concept:The data-information-knowledge hierarchy describes how raw facts are transformed into meaningful understanding.
Explanation:Data consists of raw, unprocessed facts and figures.
When data is organised, processed, and given context, it becomes information.
For example, the number
35 is raw data.
Writing "35 students passed the exam" turns that raw data into information.
When this information is understood, interpreted, and applied with experience, it becomes knowledge.
Therefore, the correct logical sequence is: Data → Information → Knowledge.
This means data leads to information, and information leads to knowledge.
Option A correctly states this relationship.
Options B, C, and D present incorrect sequences of this hierarchy.
Answer:Option A: Data leads to information and information leads to knowledge.
