What is meant by 'sight alignment'?

Sight alignment refers specifically to the relationship between the front and rear sights of a firearm. Proper sight alignment is crucial for accurate shooting, as it ensures that the shooter is looking through the rear sight with the front sight centered and level in relation to it. When the sights are aligned correctly, the shooter can aim accurately at the target. This process involves aligning the tops of the front and rear sights and placing the front sight on the intended point of impact on the target.

The other options focus on different aspects of shooting but do not define sight alignment accurately. The target and shooter's relationship pertains more to sight picture, the adjustment of the gun's barrel relates to zeroing or sight adjustment, and hand placement affects grip and control rather than sight alignment itself. Therefore, the correct focus on the front and rear sights describes what sight alignment truly means in the context of firearms training.
