What is the function of the RPG-7 booster?

The function of the RPG-7 booster is to provide initial ignition and thrust. The RPG-7, which stands for Rocket-Propelled Grenade, relies on a booster rocket to propel the grenade toward its target effectively. When the weapon is fired, the booster ignites and generates the necessary thrust to launch the grenade at high velocity. This initial thrust is crucial for achieving the desirable trajectory and range, allowing the rocket to clear the launcher and travel towards the intended target with sufficient speed.

The booster is not designed for stabilization, guidance, or smoke dispersal. Stabilization is typically achieved through other design features such as fins or aerodynamic shaping of the projectile. Guidance systems, if present, utilize different mechanisms often not present in basic models like the RPG-7. Similarly, smoke dispersal involves different components or techniques not related to the functional purpose of the booster itself. Thus, option B accurately captures the primary role of the booster in the RPG-7 system.
