    Dear , Try to check by adding water to each of these. CO and NO don't make any sense regarding anhydrides. B203 is boric anhydride: H3B03'n HBO2+ H20, 2HBO2 n B203+ H20; N205 is also anhydride:N205 +H20'n 2HNO3; S03 is also anhydride as S03+H20-->H2504; P4010 is also anhydride as P4010+6H20 n 4H3PO4; SO2 is also anhydride as SO2+H20-->H2SO3. Total=5. Keep in mind that in hydrolysis and dehydration both, the oxidation number of central atom doesn't change as you can verify by above examples. so the correct answer is 5
