Answer: A

Explanation: In space feed, the energy is distributed to the lens array in a manner analogous to point feed illuminating a reflect antenna. In constrained the power is divided into many elements under different steps. In optical feed systems power is divided in one step. Parallel plate feed uses microwave structure principles and provides efficient power division.
