AI Explanation
A) Pintle is the correct answer. The pintle nozzle requires the least maintenance among the options provided. Pintle nozzles have a simple design with a single orifice that is less prone to clogging or fouling compared to multi-hole or open nozzles. Their straightforward construction and single point of fuel flow make them more reliable and easier to maintain over time. The other options, such as single-hole, multi-hole, and open nozzles, have more complex designs with multiple openings or an exposed fuel flow path, which can lead to increased maintenance requirements to prevent issues like clogging or wear.
