(D) The inductive reactance of a coil is given by the formula $X_{L} = 2 \pi f L$,where $f$ is the frequency and $L$ is the inductance.Given that the initial inductive reactance is $X_{L1} = R = 2 \pi f L$.If the inductance is tripled $(L' = 3L)$ and the frequency is tripled $(f' = 3f)$,the new inductive reactance $X_{L2}$ is:$X_{L2} = 2 \pi f' L' = 2 \pi (3f) (3L) = 9 (2 \pi f L)$.Substituting the initial value $R = 2 \pi f L$,we get:$X_{L2} = 9R$.

The inductive reactance of a coil is $R \ \Omega$. If the inductance of the coil is tripled and the frequency of the $A.C.$ supply is also tripled,then the new inductive reactance will be:
