Another advantage is that radar fixes can be obtained quickly.

Explanation:
Radar fixes provide position updates in a short amount of time because you can measure range and bearing to known objects and plot the fix right away as you sweep. That immediacy isn’t literally instantaneous, but it’s much faster than waiting for other methods (like celestial, landmarks, or long dead-reckoning) to yield a result, and the fix can be refreshed quickly as you monitor the radar. So the best choice is the one that conveys this rapid capability. The other options imply either no delay or a much slower process, which doesn’t describe how radar fixes are typically obtained.
