(A) The mass number of an atom is defined as the sum of the number of protons and the number of neutrons in its nucleus.For Oxygen $(O)$:Atomic number $= 8$ (protons $= 8$)Number of neutrons $= 8$Mass number $= 8 + 8 = 16$For Sulphur $(S)$:Atomic number $= 16$ (protons $= 16$)Number of neutrons $= 16$Mass number $= 16 + 16 = 32$Therefore,the mass numbers are $16$ and $32$ respectively.

	$X$	$Y$
Protons $=$	$6$	$6$
Neutrons $=$	$6$	$8$
