Explanation:
Hello there!
In this case, according to the given information derived from the combustion analysis, it turns out possible for us to realize that all the carbon comes from the CO2 and all the hydrogen from the H2O, it means we can calculate their moles in the vitamin C as shown below:
Next, we calculate the grams and moles of oxygen from the grams of C and H in the sample:
Then, we divide the moles of C, H, O by 0.0165 as the fewest moles in order to calculate the correct mole ratios:
Finally, we turn them into whole number by multiplying by 3 so that the empirical formula is:

Point "C" is correct and all the remaining are false.
Note, HomeAtomic and HeteroAtomic compounds are the types of compounds, but not homogenous and heterogenous.
The classification of whipped cream is a foam.
So, option C is correct one.

Sol is a solid dispersed in the liquid . Examples includes Au , S sol in water , milk of magnesia .
The emulsion is liquid dispersed into the liquid . Example is milk
Foam is a gas dispersed into the liquid . Examples includes whipped cream , shaving cream , foam on the beer .
