pre sale...............

Answer 2

Everything in this store is for sale.

Prepositions are those words which are used to combine nouns, verbs, phrases etc. Examples : for, of, at, on, in, beside, beneath, across, inside etc

Here the right preposition that can be used is "for".

• Usually, the preposition FOR is used to show the purpose, relationship or the use of the object.
• It can be used to specify something or to put the importance of an event.
• It can be used to denote the duration or time or period to accomplish a task.
• No two prepositions can occur simultaneously because they do not give complete meaning to  the sentence.

Therefore, prepositions are connectors which are used to give a complete meaning to a sentence.
