What is the consequence of improper pre-launch checks?

Improper pre-launch checks can lead to a potential failure of a rocket launch and create significant safety hazards. This is crucial because pre-launch checks are designed to verify that all systems are functioning correctly and that the rocket is prepared for a successful flight. When these checks are neglected or performed incorrectly, it can result in malfunctions during launch, which may lead to catastrophic failures, such as loss of the vehicle, unplanned safety incidents, or even harm to individuals nearby.

The diligence in performing thorough pre-launch checks directly correlates to the integrity of the rocket components, the reliability of the launch procedures, and overall mission success. Ensuring that every aspect of the rocket's systems is operational minimizes risks and enhances both crew safety and mission objectives. Without these checks, the chances of encountering critical failures increase dramatically, underscoring why B is the correct consequence.
