Best answer
Correct answer is (a) shock wave formation

The best I can explain: Wave drag is primarily result of shock wave formation. Shock waves are very thin layer across which we can observe drastic change in the flow properties. Across shock, pressure and temperature will increase drastically. This sudden change in pressure results in the wave drag.
