Which of the following is an example of a synthesis reaction?

Explanation:
Synthesis reactions are when two or more substances combine to form a single product. The example where oxygen gas reacts with hydrogen gas to make water fits this perfectly: two reactants come together to yield one product. The other cases show different kinds of reactions: combustion typically produces multiple products, decomposition breaks one compound into parts, and displacement swaps atoms to form new substances rather than a single product. So the scenario that illustrates synthesis is the formation of water from oxygen and hydrogen.
