The meeting was cancelled because of the convocation

Analyze the question: The word in focus is "cancelled" (the underlined word, though the underline doesn't show in the text). We need the option closest in meaning to it.

Explain the concept: This tests phrasal verbs. Each option is a phrasal verb with its own meaning:

• brought up means raised (a topic) or reared (a child)
• called off means cancelled
• broke off means stopped suddenly, or detached
• phased out means gradually withdrawn or stopped over time

Solution:

1. "Cancelled" means a planned event will not take place.
2. Substitute each option into the sentence: • "The meeting was brought up because of the convocation" makes no sense. • "The meeting was called off because of the convocation" means the meeting did not hold, which matches. • "The meeting was broke off..." is also grammatically wrong, because the past participle should be "broken off", and "broke off" usually describes stopping something already in progress, such as a conversation. • "The meeting was phased out" suggests a gradual ending, which is not the case for a single meeting.

Answer: The correct option is B. called off.

Tip: "Call off" = cancel. Memorize similar pairs for JAMB: put off = postpone, call off = cancel, carry out = perform, look into = investigate. Also, if the underlined word is a past participle, check which option fits grammatically as well as in meaning.
