When a bullet strikes a surface, it generates stress that is transmitted through the material. On the side opposite the impact, tension occurs due to the rapid deceleration of the bullet and the compression that has been created at the point of entry. The dynamics of this tension can result in a potential fracture as the material may not be able to withstand the stress induced by the bullet's impact.

Tension is critical in understanding how materials react under force. When the bullet penetrates, the material experiences compressive forces at the point of impact, while the opposite side, now under tension, can exceed the strength of the material, leading to cracking or other damage. This phenomenon is particularly relevant in forensic analysis, as understanding the mechanics of how materials respond to ballistics can provide insights into the nature of the impact and help reconstruct crime scene events.

The other answer choices do not directly address the specific mechanical response of the material on the opposite side of the impact. For example, while some surfaces may absorb energy or compress, they do not primarily experience tension leading to fracture the same way as described in the question context. Reinforcement is not typically a result of impact but would generally relate to structural enhancements that prevent failure, which is not applicable to this scenario.
