To solve such this we must know the concept of synthesis reaction. Therefore, the correct option is option A that is It represents a synthesis reaction because two reactants form one product.
What is chemical reaction?
Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
