Best answer
The correct option is (a) Parallel feed

Best explanation: In parallel feed, a number of radiators are combined into sub-arrays and then to elements in series or center fed. In series end fed, the radiator is placed at the end of the array and its electrical path length depends on the frequency.In optical feed systems power is divided in one step.
