A.filtration
B. freeze-drying
C. osmosis
D. desiccation

Answer 1

A is the right answer

Answer 2

Microbes can be removed from a liquid by filtration. (option A)

• Filtration is the process of removing dirt and microorganisms from liquids through a porous filter medium that only allows the liquid component through.
• Gravity filtration is the most common technique where the mixture is poured from a higher region to a lower region through a filter medium. The action of gravity separates the solid components.
• Industrial filtration involves usage of a pump to force the mixture through the filter element, hence separating the components. This is also called mechanical filtration.
