The insoluble solid particles can be separated from the liquid by filtration. A filter paper is made into a cone & placed in a funnel, the liquid flows through the cone and solid particles remain in the cone.

This term is not directly related to the process of filtration. Filtration involves separating particles from liquids based on the size of the particles and their solubility, not their arrangement in a radial pattern. 

This term is not directly related to the process of filtration. Filtration is based on the size and solubility of particles, not their angular orientation. 

This is the correct option. The process of filtration is used to separate particles that are insoluble in the liquid medium. Insoluble particles, such as solid particles or precipitates, can be separated from a liquid by passing the mixture through a filter medium, which allows the liquid to pass through while retaining the solid particles. 

Soluble particles dissolve in a liquid and do not need to be separated by filtration. Filtration is specifically used to separate insoluble particles from liquids.
