Answer:
The correct answer is filtration.
Step-by-step explanation:
Filtration refers to a physical procedure, which is used to distinguish two or more constituents because of their distinct size of particulate or unit. On the other hand, distillation refers to a chemical procedure, which is used to distinguish two or more constituents because of the difference between their boiling points, however, this process is generally used in the case of liquids.
Thus, it is clear that with the help of the filtration process, one can separate the acorns, leaves and twigs from the soil. Hence, the correct answer is filtration.
