Take another look at the sentence:
When Delores realized that her father had made lima beans and rice for dinner, she __________, claimed to feel nauseous, and excused herself from the table. The bag of stale popcorn in her room would tide her over until breakfast.
The blank needs to begin with a simple past tense verb. You chose was clutching ..., which uses the past progressive tense and thus causes a parallelism error.
Before you continue, review the rules for parallel structure.
