Which option is not one of the five Vs of big data?

• A. Volume
• B. Velocity
• C. Density
• D. Veracity

Answer: (C)

Big data is described by several key characteristics known as the five Vs: volume (amount of data), velocity (speed of data generation and processing), variety (different data types and sources), veracity (data accuracy and trustworthiness), and value (usefulness of insights). Density isn’t part of this standard set, so it doesn’t describe a core big data attribute. Therefore, density is the option that isn’t one of the five Vs. The others—volume, velocity, and veracity—fit because they correspond to the amount of data, the speed of data flow, and the reliability of the data, respectively; value is the usefulness gained from analyzing the data.
