Answer :
Ranking from the smallest to the largest moment of inertia ; I₂ < I₁ < I₃
Although the question is incomplete the missing part is gotten online and attached below is the missing diagram
Given that the formula for moment of inertia
I = m₁r₂² + m₂r₂² + m₃r₃³ + -----
when we apply this formula to the moments of inertia
I₁ = m*(r/2)² + m*(r/2)² = [tex]m*r^2 / 2[/tex]
I₂ = 2m * (r/4)² + m*(r/4)² = [tex]3* m*r^2/16[/tex]
I₃ = (m/2)*r² + (m/2)*r² = [tex]m*r^2[/tex]
Therefore from the given values gotten from the summation of the various moments of inertia when ranking the moment of inertia from the smallest to the largest we will have I₂ < I₁ < I₃
Hence we can conclude that ranking from the smallest to the largest moment of inertia is I₂ < I₁ < I₃

[tex]\rm I_3>I_1>I_2[/tex]
Given :
Pair 1 --
Mass - m , m and
Radius - R
Pair 2 --
Mass - 2m , m and
Radius - [tex]\dfrac{R}{2}[/tex]
Pair 3 --
Mass - [tex]\rm \dfrac{m}{2}\;'\;\dfrac{m}{2}[/tex] and
Radius - 2R
Solution :
We know that moment of inertia is,
[tex]\rm I = m_1r_1^2+m_2r_2^2+m_3r_3^2+...[/tex]
Now for pair 1,
[tex]\rm I_1 = mR^2+mR^2 = 2mR^2[/tex] ---- (1)
Now for pair 2,
[tex]\rm I_2 = 2m(\dfrac{R}{2})^2+m(\dfrac{R}{2})^2 = \dfrac{3mR^2}{4}[/tex] ----- (2)
Now for pair 3,
[tex]\rm I_3 = \dfrac{m}{2}(2R)^2+\dfrac{m}{2}(2R)^2 = 4mR^2[/tex] ------ (3)
So, from equation (1), (2) and (3) we get,
[tex]\rm I_3>I_1>I_2[/tex]
