The phrase "put aside" is commonly used to indicate the act of saving or reserving something for a specific purpose. In the context of the sentence, "Father put aside some amount of money for the education of his daughter," it implies that the father has intentionally set aside or earmarked money specifically for his daughter's education, indicating foresight and responsibility.

Other options have different meanings that do not fit the context appropriately:

- **A) up** typically suggests an increase or intensification but does not convey the idea of reserving money.
- **C) into** implies movement towards a place but lacks the nuance of saving or reserving money for a future goal.
- **D) on** can suggest a dependency or focus on something but does not clearly denote the act of saving money for a specific use.

Thus, "put aside" effectively captures the intention behind the father's action, making it the most fitting choice among the options provided.
