In data storytelling, a narrative is constructed using data to elucidate trends, patterns, and insights. Raw data serves as the empirical evidence substantiating the narrative and ensuring its credibility. A narrative devoid of data constitutes mere opinion or conjecture. The integration of narrative with data facilitates audience comprehension of the rationale underpinning the insights. This methodology establishes the story's trustworthiness and applicability by grounding it in factual evidence. Scores or probabilities are derived from data, yet the fundamental basis remains the data itself. A project encompasses the broader context of data generation and utilization, rather than being an appendage to the narrative. Consequently, option (C) Data represents the accurate choice.
