How to approach this question
Identify the keywords: 'structured/unstructured/video' points to one V, and 'reliability/interference' points to another.
Full Answer
Variety refers to the different forms of data (structured logs, unstructured text, video). Veracity refers to the trustworthiness and reliability of the data, which is questioned here due to electromagnetic interference.
Common mistakes
Selecting Volume just because 'millions' is mentioned, missing the more explicit focus on data types and reliability.
