Rescheduling might involve adjusting task dates, but it doesn't inherently compress the schedule when no extra time is given and scope has increased.

Crashing is a schedule compression technique that involves adding resources to critical path activities to shorten the overall project duration at an increased cost. In this scenario, with no extra time but approved changes, crashing helps meet the deadline by accelerating specific tasks.

Rebaselining involves formally approving a new project baseline, often due to significant changes, but it is not a direct technique for compressing the schedule itself.

Control scope is a process to manage project scope, ensuring that only approved work is performed, rather than a technique to compress the schedule.
