Correct Option: A. failed Explanation of the Correct Answer The phrase "fell through" is an idiomatic expression in English that means something did not happen as planned or failed to be successful. When we say that "all his plans fell through," we are indicating that none of his plans came to fruition; they all failed to materialize.

1. Understanding the Idiom:
2. "Fell through" is commonly used to describe situations where expectations or arrangements do not work out. For example, if someone had a plan to go on a trip but it was canceled, we could say that the trip "fell through."
3. This idiom conveys a sense of disappointment or failure, which aligns perfectly with the context of the sentence.
4. Contextual Clarity:
5. The sentence implies that the plans were likely anticipated to succeed but ultimately did not. The use of "fell through" suggests a sudden or unexpected failure, reinforcing the idea that the plans were not just unsuccessful but also perhaps surprising in their failure.

Why the Other Options Are Incorrect B. were accomplished - This option suggests that the plans were successfully completed. However, this contradicts the meaning of "fell through," which indicates failure rather than success. If the plans were accomplished, they would not have "fallen through." C. had to be reviewed - This option implies that the plans were not necessarily failures but required further examination or modification. While reviewing plans can be a part of the planning process, it does not capture the essence of "falling through," which indicates a complete failure to execute the plans. D. were rejected - This option suggests that the plans were actively turned down or dismissed. While rejection can lead to plans not being executed, "fell through" does not specifically imply that the plans were rejected; rather, it indicates that they simply did not succeed. Therefore, this option does not accurately reflect the meaning of the idiom. Summary of Key Points
