I am afraid the deal fell off.

Answer 2

Answer:

The right answer is ‘I am afraid the deal fell through’

Explanation:

'Through' is a preposition. A 'preposition' is a word that precedes a 'noun or pronoun.' A preposition is used in 'relation' to another word in the clause or a sentence.  

In a way, prepositions can be said to be words that help in joining a sentence. They are therefore used before a 'noun' or 'pronoun' and is in 'relation' to another word in the sentence.
