B. 4   and   2   and   4   and   2 .
Step-by-step solution
As we know that, the peroxodisulfuric acid and pyrosulfuric acid are the examples of oxyacid and both contain sulfur oxygen and sulfur hydrogen bond. In the oxyacids, the oxygen is the main element. Peroxodisulphuric acid Pyrosulphuric acid The number of S=O and S−OH bonds present in peroxodisulphuric acid and pyrosulphuric acid respectively are (4 and 2) and (4 and 2).
