How to approach this question
Match the description of 'different data formats' to the correct 'V' of Big Data.
Full Answer
C.Variety✓ Correct
The 3 Vs of Big Data are Volume (amount), Velocity (speed), and Variety (types). Because the retailer is mixing structured data (sales numbers) with unstructured data (social media text, video feeds), this specifically illustrates 'Variety'.
Common mistakes
Selecting Volume because 'petabytes' is mentioned. Read the question carefully: it asks what the 'inclusion of text, video, and numerical data' illustrates.
