Hey there!
(KEY POINT HERE)
[tex]\searrow\searrow\searrow\searrow\searrow\searrow\searrow\searrow\searrow\searrow \ \swarrow\swarrow\swarrow\swarrow\swarrow\swarrow\swarrow\swarrow\swarrow \\ \\ \boxed{(((((4* \frac{(M^3)}{3} *(m^2))*n)*9)* \frac{n^2}{30} *m^2)*n^2}[/tex]
Now that we have considered that equation above, we would now understand what is clear to be your (correct answer).
Your correct answer to this question listed above would be (option B).
[tex]\boxed{\boxed{2 m / 5 n}}[/tex]
I hope this helps you!
