Correct Answer: Option C — can be adjusted or varied

An arrow drawn at a 45-degree angle across a hydraulic component symbol is the standard ISO/ANSI notation for adjustability. This indicates that the component, such as a relief valve or variable displacement pump, can be manually or automatically adjusted to change its operating parameters during system service.
