This ensures data integrity and reliability during concurrent read and write operations. While Delta Lake also offers other benefits like flexible schemas and scalable storage, ACID transactions are specifically highlighted as a core differentiator from common data lake solutions. The community discussion confirms this with upvoted comments supporting answer A.
