What must be analyzed using powerful analytic tools?

Big datamust be analyzed using powerful analytic tools due to its volume, velocity, and variety. In data-driven decision making, traditional tools are often insufficient for processing massive, complex datasets generated from digital platforms, sensors, and transactions.

Big data requires advanced computing power, specialized software, and sophisticated algorithms to extract meaningful insights. Inferential statistics and small datasets can often be handled with conventional statistical tools.

Therefore, the correct answer isC, big data.
