Janet exclaimed that she had lost all her belongings at the airport that morning.

The correct answer is D. Janet said, “I lost all my belongings at the airport this morning.”

The other options are incorrect because they use the past perfect tense, which is used to talk about something that happened before another event in the past. In this case, Janet is talking about something that happened in the past (she lost her belongings), and she is not talking about something that happened before another event in the past.

Here is a brief explanation of each option:

• A. Janet said, “I had to lose all my belongings at the airport this morning.” This is incorrect because it uses the past perfect tense. Janet is not talking about something that happened before another event in the past. She is simply talking about something that happened in the past.
• B. Janet said, “I lost all my belongings at the airport this morning.” This is the correct answer because it uses the simple past tense. Janet is talking about something that happened in the past.
• C. Janet said, “I had lost all my belongings at the airport this morning.” This is incorrect because it uses the past perfect tense. Janet is not talking about something that happened before another event in the past. She is simply talking about something that happened in the past.
