$\frac{(\text{t}_1+\text{t}_2)}{2}.$
$\frac{\text{t}_1\text{t}_2}{(\text{t}_2-\text{t})}.$
$\frac{\text{t}_1\text{t}_2}{(\text{t}_2+\text{t}_1)}.$
$\text{t}_1-\text{t}_2.$
Assertion $A :$ Moment of inertia of a circular disc of mass $'M'$ and radius $'R'$ about $X, Y$ axes (passing through its plane) and $Z-$axis which is perpendicular to its plane were found to be $I_{x}, I_{y}$ and ${I}_{z}$ respectively. The respective radii of gyration about all the three axes will be the same.
Reason $R$ : A rigid body making rotational motion has fixed mass and shape.
In the light of the above statements, choose the most appropriate answer from the options given below :
