The reaction Fe + O₂ → Fe₂O₃ is an example of Combination reaction.
Hence, Option (A) is correct answer.
What is a Chemical reaction ?
A chemical reaction is a process in which chemical bonds between atoms to break and reorganize, to form other new substances.
Now lets check all options one by one
Option (A): Combination Reaction
A Combination reaction is a chemical reaction where two or more substances react to produce a new compound.
In the given reaction new product is formed which is Fe₂O₃. So it is a Combination reaction.
Hence, option (A) is correct.
Option (B): Decomposition Reaction
A Decomposition reaction is a chemical reaction in which one reactant breaks down to form a two or more products.
In the given reaction a single new product is formed which is Fe₂O₃, so it is not a decomposition reaction.
Hence, option (B) is incorrect.
Option (C): Aqueous reaction
An aqueous reaction is a chemical reaction which dispersed in water that means a reaction takes place in water.
In the given reaction the reaction does not takes place in water. So it is not an Aqueous reaction.
Hence, Option (C) is incorrect.
Option (D): Single replacement
A Single replacement reaction is a chemical reaction in which one element replaces the another element in a compound. It is also called Single displacement reaction.
In the given reaction no element replaces with other element here a new compound formed. So it is not a Single replacement reaction.
Hence, option (D) is incorrect.
Thus, from the above conclusion we can say that The reaction Fe + O₂ → Fe₂O₃ is an example of Combination reaction.
Hence, Option (A) is correct answer.
