The correct Answer was: "A" MRA

 

MRA (Minimum Reception Altitude) is the lowest altitude allowing adequate reception for identifying certain radio fixes by use of radials from two different omnis. MRA does not apply when identifying a fix with DME.

 

MCA (Minimum Crossing Altitude) is the minimum altitude at which certain fixes MUST BE CROSSED in specified directions of flight to accomodate a different (and Higher) MEA.

 

MOCA (Minimum ORbstruction Clearance Altitude) is the specified minimum altitude BETWEEN radio fixes which...

Meets obstruction requirements, but assures navigational signal reception...ONLY WITHIN 22 NAUTICAL MILES OF THE VOR.
