made

The most appropriate option to fill in the blank is made.

The sentence "I do not know what made my father choose that particular college" means that the speaker is not sure what factors or reasons influenced their father's decision to choose that particular college. The word "made" is the most appropriate word to use in the blank because it accurately reflects the fact that the father's decision was influenced by something.

The other options are not as appropriate.

• The word "happened" is used to talk about an event that took place. This does not make sense in the context of the sentence, as the speaker is not asking about an event that took place, but about a reason or factor that influenced the father's decision.
• The word "controlled" is used to talk about someone or something having power over something else. This does not make sense in the context of the sentence, as the speaker is not asking about someone or something having power over the father's decision, but about a reason or factor that influenced the father's decision.
• The word "asked" is used to talk about someone asking a question. This does not make sense in the context of the sentence, as the speaker is not asking a question, but is expressing their uncertainty about the reasons for the father's decision.
