Solution
The correct option is B Both a and b
The process of separating insoluble substances which are heavier than liquid by allowing them to settle down on their own due to gravity is called sedimentation.
The particles which settle down during sedimentation are called sediments.
Decantation follows sedimentation.
In this process, the clear upper liquid is poured out from the container without disturbing the sediment. The upper clear liquid is called supernatant. Hence, the above example involves the sedimentation and decantation process.
