Reveal answer & explanation
Correct answer: B) Velocity
Explanation
Velocity refers to the speed at which data is generated and must be captured and processed, often in real time. Volume relates to the sheer quantity of data, variety to the range of formats (structured and unstructured), and veracity to the reliability or trustworthiness of the data. The emphasis here is on near-instant analysis, so velocity is the best description.
