The most suitable word that completes the sentence is option C: "had just left". This is because the sentence is in the past tense, and we need to use a verb tense that indicates an action that was completed before another action in the past. The past perfect tense "had just left" is used to show that an action (leaving the scene) was completed before another action (the explosion) occurred. The other options, such as "has just left", "just left", and "is just leaving", do not fit the context of the sentence and do not show that the action of leaving the scene was completed before the explosion.
