It __________ true! What do you mean she’s leaving?A.haven’t beenB.couldn’t beC.shouldn’t beD.hasn’t been

To solve the question, we need to fill in the blank with the most appropriate option to complete the sentence grammatically and logically.

1. Break Down the Problem

   • The sentence structure indicates that we are looking for a negative form of a verb that relates to the state of truth about the situation described.

2. Relevant Concepts

   • Each option presents a different verb form:
     • A. haven’t been (present perfect)
     • B. couldn’t be (modal verb indicating impossibility)
     • C. shouldn’t be (modal verb indicating obligation or expectation)
     • D. hasn’t been (present perfect)

3. Analysis and Detail

   • The context of the sentence suggests a sense of disbelief or surprise regarding the news of someone leaving.
   • Option A ("haven’t been") suggests a present perfect experience but doesn’t fit the realm of disbelief.
   • Option B ("couldn’t be") contemplates the idea of impossibility, aligning well with expressing disbelief.
   • Option C ("shouldn’t be") implies expectation against reality but does not convey disbelief as strongly as option B.
   • Option D ("hasn’t been") indicates non-occurrence but doesn’t capture the feeling of shock or disbelief either.

4. Verify and Summarize

   • Considering the analysis, the most suitable option that conveys astonishment or disbelief about the situation is option B: "couldn’t be."

Final Answer

B. couldn't be
