Answer:
The  moment of inertia is  
Explanation:
From the question we are told that 
     The  frequency is  
     The  mass of the pendulum is  
     The  location of the pivot from the center is 
      
Generally the period of the simple harmonic motion is mathematically represented as 
         
Where I is the moment of inertia about the pivot point , so making I the subject of the formula it 
=>    ![I =  [ \frac{T}{2 \pi } ]^2 *  m*  g * d](https://tex.z-dn.net/?f=I%20%3D%20%20%5B%20%5Cfrac%7BT%7D%7B2%20%5Cpi%20%7D%20%5D%5E2%20%2A%20%20m%2A%20%20g%20%2A%20d)
But the period of this simple harmonic motion can also be represented mathematically as 
         
substituting values 
       
       
So 
       ![I =  [ \frac{2.174}{2 * 3.142 } ]^2 *   2.40*  9.8 * 0.380](https://tex.z-dn.net/?f=I%20%3D%20%20%5B%20%5Cfrac%7B2.174%7D%7B2%20%2A%203.142%20%7D%20%5D%5E2%20%2A%20%20%202.40%2A%20%209.8%20%2A%200.380)

its either a or d however i say the best choice is d
 
        
             
        
        
        
I think this is AWESOME, but I think the last sentence of your conclusion is a bit off. <span> "If someone has an allergy to oil then they can still eat cake because applesauce makes an amazing substitute for oil." I think that you should say "This recipe is great for those who cannot eat/drink oil, the applesauce is an amazing substitute for oil."

Sorta stuck between minerals and lips 
Minerals; Minerals are, unlike vitamins, inorganic substances. All vitamins are identified as key nutrients: the body cannot produce them and so they must be obtained through diet; minerals are similarly identified as key nutrients. Vitamins and minerals are equally essential for the healthy functioning of the body. 
But then there’s lipids
Lipids; Lipids are a group of structurally and functionally diverse organic compounds that are insoluble in water. Certain classes of lipids, such as fats, phospholipids

wavelength = speed/frequency 
 ==> freq. = speed/wavelength = 342.5/0.75 = 456.67 Hz.
