When considering the behavior of a rocket in flight, it's crucial to assess the relationship between the center of gravity (CG) and the center of pressure (CP). In this scenario, the CG is positioned ten inches forward of the CP. This significant forward placement can influence how the rocket stabilizes itself after launch.

When a rocket has its CG so far forward compared to its CP, it tends to be more stable against crosswinds. The aerodynamic forces that act on the rocket will result in it weathercocking into the wind, aligning its flight path with the direction of the oncoming airflow. This behavior is a natural consequence of stability dynamics; with the CG ahead of the CP, the rocket will pivot toward the wind instead of simply continuing along its initial trajectory.

In contrast, other options suggest different phenomena which don’t adequately address the implications of the CG being forward relative to the CP. For instance, the idea of "skywriting" relates to instability but does not apply here, as the configuration points to greater stability. Similarly, while a longer rocket might fly slower, this specific aspect does not impact weathercocking, nor does it necessitate that the rocket will fly straight without external influences, which is not guaranteed in changing wind conditions.
