The chemical reaction involves the products and the reactants. The image is neither synthesis nor decomposition as the two products are formed from two reactants. Thus, option A is correct.
What is a chemical reaction?
A chemical reaction includes the chemical interaction between the reactants to yield the products. In a synthesis reaction, two reactants interact to produce a different molecule or compound.
In a decomposition reaction, a reactant undergoes splitting to produce products and energy. But in the image two reactants produces two products that neither of the reaction shows.
This type of reaction is seen as the single replacement reaction where the more reactive element displaces the less reactive from the compound to form the new molecule.
Therefore, option a. Maya's picture represents a single replacement reaction but not a synthesis or decomposition reaction.
