The correct option is D K,L,M::2,8,6
Sulphur is a multivalent non-metal, abundant, tasteless and and odourless. In its native form sulphur is a yellow crystalline solid. In nature it occurs as the pure element or as sulphide and sulphate minerals. Although sulphur is infamous for its smell, frequently compare to rotten eggs, that odour is actually characteristic of hydrogen sulphide. Actually from ferrous sulphate we get sulphur dioxide. Basically sulphur forms two oxide that is SO2,SO3.These are very harmful for our environment because these form sulphuric acid and sulphurous acid . Hence the given element is sulphur with atomic number 16. Hence the electronic configuration is 2, 8, 6.
