Which statement correctly describes the open-sight rule for 10-Meter Air Pistol?

• A. Open sights are prohibited; only peep sights are allowed.
• B. Open sights may be used but cannot be adjusted for elevation or windage.
• C. Open sights are allowed and may be used for elevation and windage.
• D. Open sights are optional and not used for scoring.

Answer: (C)

The main idea being tested is what sights are allowed and how they are used in a 10-meter air pistol event. Open sights are permitted, and you can use them to adjust for elevation (up and down) and windage (left and right). This lets you zero the pistol so your shots land where you aim on the 10-meter target, which is how scoring is determined. The statement that open sights are allowed and may be adjusted for elevation and windage matches how competitors set up and fine-tune their aim before or between series. The other options describe prohibitions or setups that aren’t part of standard 10-meter air pistol rules, or misstate how sighting affects scoring.
