Fill in the gap(s) with the most appropriate option from the list following the gap(s).
The minister can't come today because he has _____ engagement?
Answer Details
The sentence is stating that the minister is unable to come today because he has an engagement. The missing word needed to complete the sentence is "a prior engagement."
This means that the minister had already planned or scheduled an appointment or activity before the current one, which makes it impossible for him to attend the present event.
In other words, the minister had a commitment that he made earlier, which he cannot break, and therefore, he cannot attend the engagement that is happening today.
