The correct option is D decantation
The explanation for the correct option- (D) Decantation
Decantation – the process of pouring off the liquid layer formed above the sediment layer without disturbing the bottom sediment layer. This method can also be used to separate two immiscible layers of liquids.
This method does not require any kind of assembly or instrumentation.
The explanation for the incorrect options-
(A) Filtration – The process by which the insoluble or suspended particles of a mixture are separated from the liquid by using a porous membrane called a filter is called filtration. the method requires a filtration assembly.
For example – the separation of sand and clay particles from water by passing it through a filter paper.
(B) Distillation – the process by which a soluble liquid can be separated from a solution by first converting it into vapors by evaporation and then cooling and collecting the vapors by condensation in another container is called distillation. The technique requires various apparatus and the whole assembly is called a distillery.
For example – distilled water can be obtained from tap water by the process of distillation.
(C) Centrifugation – the process of separation of finely suspended solids from a liquid by rotating the mixture at a very high speed in an instrument called a centrifuge machine is called centrifugation.
For example – the separation of cream from milk.
Hence, option (D) is correct. decantation is the odd one out because this method does not require any kind of assembly or instrumentation.
