Show answer & explanation
Correct answer: A
In database transaction scheduling, conflict serializability is a stricter condition than view serializability. Every schedule that is conflict serializable is guaranteed to be view serializable. However, the reverse is not true; there exist view serializable schedules that are not conflict serializable (often involving blind writes). Therefore, the set of conflict serializable schedules is a proper subset of view serializable schedules.
