Answer is Right!
Answer is Wrong!
The correct answer is: The house is on fire! Send for the Fire Brigade.
The word “on” is used to describe the location of something. In this case, the house is on fire. The word “for” is used to indicate a purpose or destination. In this case, the Fire Brigade is being sent to the house to put out the fire.
The other options are incorrect because they do not make sense in the context of the sentence. The word “in” is used to describe the interior of something. In this case, the house is not on the inside of fire. The word “at” is used to describe a location or position. In this case, the house is not at fire. The word “of” is used to indicate possession or association. In this case, the house is not of fire.
I hope this helps!
