The correct form of the verb to fill in the blank is "had met." Here is why:
Past Perfect Tense:
The past perfect tense is used to describe an action that happened before another action in the past. In this sentence, the speaker suddenly realized something, which means the realization happened in the past. Therefore, the action of meeting the person must have happened before the realization.

Here are the key points to understand why "had met" is the correct form:
- The verb "meet" is in the past participle form "met" because it is an irregular verb.
- The auxiliary verb "had" is used to form the past perfect tense.
- The past perfect tense is formed by combining the auxiliary verb "had" with the past participle form of the main verb.
- The use of the past perfect tense indicates that the meeting happened before the realization.
Example:
To further illustrate the use of "had met," consider the following example:
- I suddenly realized that I had met her at school.

To answer this question, we need to determine the correct form of the verb that should be used in the given sentence. Let's analyze each option:
A: just turned out
- This option is the correct answer. The verb phrase "just turned out" is in the past simple tense, indicating a completed action in the past.
