The correct option is 'B'.
A double displacement reaction is a type of chemical reaction in which two reactant molecules exchange their partner ion, resulting in the formation of two new compounds. In this type of reaction, the positive ion of one reactant molecule is exchanged with the negative ion of the other reactant molecule, resulting in the formation of two new compounds.
For example, in the reaction between barium chloride and sodium sulfate, the barium ion (Ba2+) and the chloride ion (Cl-) from one molecule switch places with the sodium ion (Na+) and the sulfate ion (SO42-) from the other molecule, resulting in the formation of barium sulfate and sodium chloride.
BaCl2 + Na2SO4 → BaSO4 + 2NaCl
It is worth noting that, option 'C' displacement reaction is also a correct answer as it refers to a reaction in which an atom or ion of one element is replaced by another element and one product is formed.
