Which of the following is not a feature of DBMS?

Step 1: DBMS (Database Management System) is designed to manage data efficiently with features like reduced redundancy, multi-user access, and ACID properties. Step 2: Option A (Minimum duplication and redundancy) is a key feature of DBMS, so it is not the correct answer. Step 3: Option B (Single-user access only) is not a feature of DBMS, as DBMS supports concurrent access by multiple users. Step 4: Option C (Support ACID property) is a standard feature of DBMS, so it is not the correct answer. Step 5: Option D (More than one of the above) is incorrect because only one option (B) is not a feature. Step 6: Option E (None of the above) is incorrect because option B is not a feature of DBMS.
