Question
Let I1 an I2 be the moments of inertia of two bodies of identical geometrical shape, the first made of aluminium and the second of iron.
Options
I1 < I2
I1 = I2
I1 > I2
relation between I1 and I2 depends on the actual shapes of the bodies

Solution
I1 < I2
In the given case, we have
MOI
\[\propto\] Density
The density of iron is more; therefore, I2 will be greater.
