Answer: The correct answer is Option 1.

Step-by-step explanation:

A double displacement reaction is defined as the reaction in which exchange of ions takes place. The general equation for the reaction follows:

$AB+CD\rightarrow AD+CB$

During this reaction, one of the product formed is always a salt.

A gas is formed in a single displacement reaction and not in double displacement reaction.

A precipitate is formed in some of the double displacement reaction.

Water is formed in neutralization reaction when an acid reacts with a base to produce a salt and water.

Hence, the correct answer is Option 1.
