Hint:The chemical symbol for an element is usually two letters long. The first letter of every chemical symbol is a capital letter and the second letter is a small letter.

The chemical symbol is used to represent an atom or an element. The chemical symbol of an element usually consists of one or two letters from the Latin alphabet and the first letter is always capital. There are many sources from which the symbols are derived, it includes Greek name of an element or German name etc. For example: the symbol for lead is Pb and it is derived from the Latin name of lead with is plumbum, the symbol for tungsten is W and it is derived from the German name of tungsten which is Wolfram etc.
The most common form of sulphur is composed of the molecules that consist of eight atoms of sulphur and the molecular formula is ${{S}_{8}}$.
Now we know that,
Atomic number of sulphur = 16
Atomic mass of sulphur = 32g
Molar mass of sulphur =$8\times 32=256$

Hence, the correct answer is option (D).
