Choose the best option to complete the following sentence:

The fear that COVID has broken ________ in our city is not unfounded.

out

The correct answer is Option (4) - out

The correct phrasal verb here is "broken out," which means to start suddenly or spread unexpectedly, typically used for diseases, conflicts, or disasters.

• "Broken out" fits the context because it refers to the sudden onset or spread of COVID in the city.

Other options are incorrect:

• "Broken up" → Refers to separating or ending something, e.g., a relationship or a gathering.
• "Broken about" → Not a valid phrasal verb in this context.
• "Broken down" → Refers to mechanical failure or emotional collapse, not the spread of a disease.
