Explanation:
The question is incomplete; as the mixtures are not given.
However, I'll give a general explanation on how to go about it and I'll also give an example.
The percentage of a component in a mixture is calculated as:

Where
E = Amount of element/component
T = Amount of all elements/components
Take for instance:
In 
The amount of all elements is: (i.e formula mass of
)



The amount of calcium is: (i.e formula mass of calcium)



So, the percentage component of calcium is:




The amount of hydrogen is:



So, the percentage component of hydrogen is:




Similarly, for oxygen:
The amount of oxygen is:



So, the percentage component of oxygen is:




The answer is B, the second choice
In celite filtration, diatomaceous earth is used to filter a solution containing very small particles that may pass through an ordinary filter. Hydrochloric acid is added after the celite filtration to remove the remaining particles in the filtration set-up. If the amount of acid added is not enough, it may cause discrepancies in the results.
