Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1, i.e., triggered.
Filler Concept: The sentence is in past tense, so the verb should match that tense to describe a completed action.
Grammatical Explanation:
triggered (simple past) correctly fits the timeline of the event.
was triggered makes the sentence passive, which doesn’t fit here.
has triggered is present perfect, but the rest of the sentence is in past tense.
trigger is base form and grammatically incorrect here.
Correction: triggered
Final Sentence: …and triggered a heart attack in one elderly woman who died soon after she stepped off a plane.
Conclusion: The correct option is triggered.
