Explanation
Delta Lake is specifically designed to unify batch and streaming data processing on the same table, using features like structured streaming with exactly-once semantics. This means teams can write streaming data and read it with batch queries without managing separate pipelines. Option A (multiple languages) is a Databricks notebook/runtime feature, not Delta Lake specifically. Option B (real-time collaboration) is a notebook feature. Option C (query failure alerts) is a Databricks SQL feature. Option E (distributed operations) is provided by Apache Spark, not Delta Lake itself.
