Let us examine the other answer choices.

→Let us examine the first answer choice given:

   The phrase "in the end" modifies the word "needed".

      → This is incorrect; since "needed" is not a noun or pronoun. As such,    
           this answer choice given is incorrect; since the phrase "in the end" is             NOT an 'adjective phrase' that modifies the particular word: "needed",

→ Let us examine the third answer choice given:

The phrase "The wait was long" modifies the word "frustrations".

     → This is incorrect. The phrase, "The wait was long" does not modify the noun "frustrations."

The phrase "we needed" modifies the word "what".

     → This is is incorrect.  The phrase "we needed" is NOT an "adjective phrase".
