Solution

The correct option is C cannot be obtained
Since no information is provided on shape of the bodies, the ratio of the masses can not be determined.
$I_{A} = I_{B}$
$∴ m_{A} k_{A}^{2} = m_{B} k_{B}^{2}$
From the above, we can not determine the ratio of masses unless we know $\frac{k_{A}}{k_{B}}$
