As per given data, compound A on ozonolysis give two moles of aldehyde, having molar mass 44u. It indicates that the compound has an identical structure around (both sides) a double bond. So, the possible general structure of
A = YC=CY
There are eight C-H sigma bonds, it  means eight Hydrogen atoms in the structure A. Also, three C-C bonds, it indicates the presence of four Carbon atom in A.
Now, by combining all the observation, the structure of the A would be-


Ozonolysis reaction is shown below-
