Step 1: Differentiate Ex-ante and Ex-post.
- Ex-ante: Represents projected or anticipated values prior to an occurrence (e.g., intended investment).
- Ex-post: Represents actual measured values subsequent to an occurrence (e.g., realized investment).
Step 2: Integrate into the query.
The term “Ex-post” unequivocally signifies “actual outcomes” in reality, distinct from intentions.
Step 3: Discard incorrect choices.
- (B) Future projection → temporal misalignment, incorrect.
- (C) Intended plan → Ex-ante classification, incorrect.
- (D) Prescriptive plan → normative judgment, incorrect.
Final Determination: \[\boxed{\text{What has transpired}}\]
