Ex-post is depicted by which of the following ........

What actually has happened.

The correct answer is Option (1) → What actually has happened.

Ex-post refers to what has actually occurred in the economy, based on realized data. It is used to describe actual outcomes such as actual savings, investment, income, or production, as opposed to planned or intended values. In contrast, ex-ante refers to what is expected or planned to happen. So, ex-post captures the factual, historical data — in other words, "what actually has happened."
