067B D
 When Inmarsat-B and Inmarsat-C terminals are compared:
a) Inmarsat-B antennas are bulkier, but omni-directional, while Inmarsat-C antennas are smaller and parabolic, for aiming at the satellite. 
b) Inmarsat-B antennas are parabolic and smaller for higher gain, while Inmarsat-C antennas are larger but omni-directional.
c) Inmarsat-C antennas are smaller, but omni-directional, while Inmarsat-B antennas are parabolic for lower gain.
d) None of the above
