Correct Answer:
Radiarc
Explanation:
The main idea here is how boomless sprayers deliver coverage. A boomless system uses a cluster of straight-stream nozzles arranged around a central hub, and the assembly oscillates to sweep a wide area. That finger-like arrangement of multiple tips and the back-and-forth motion create a broad spray pattern without a traditional boom. This description matches Radiarc, a known boomless setup that uses several straight-stream tips around a central point and sweeps to cover ground. Directa-Spra is a different spray system with its own pattern, CDA describes another configuration, and a backpack sprayer is handheld and lacks the multi-nozzle finger cluster and oscillation characteristic of boomless devices.
