Best answer
The correct choice is (a) True

Explanation: Based on the relation between induced power per unit thrust and the disk loading, \(\frac {P}{T}=\sqrt {\frac {T}{2\rho A}}\) we notice that in order to have a small value of P/T which is a requirement for high hovering efficiency, we need to have a small value of T/A which is known as disk loading.
