Explanation:

To solve this, we analyze each option:

• Option a: Acid - base reactions involve acids and bases reacting, not the opposite of decomposition.
• Option b: Synthesis (combination) reactions involve combining substances to form a new compound, while decomposition breaks a compound into simpler substances. So synthesis is the opposite of decomposition.
• Option c: Combustion is a reaction with oxygen, usually producing energy, not related to being the opposite of decomposition.

Answer:

b. Synthesis
