To determine the type of reaction represented by [tex]\( \text{CaO} + \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 \)[/tex], we should analyze the components and how they interact.

Here are the steps to identify the reaction type:

1. Identify the Reactants:
- [tex]\( \text{CaO} \)[/tex] (calcium oxide)
- [tex]\( \text{H}_2\text{O} \)[/tex] (water)

2. Identify the Product:
- [tex]\( \text{Ca(OH)}_2 \)[/tex] (calcium hydroxide)

3. Type of Simple Reaction to Form the Product:
- The reaction involves calcium oxide (a metal oxide) reacting with water, resulting in the formation of calcium hydroxide.

4. Classify the Reaction:
- In this scenario, two reactants combine to form a single, more complex product. This fits the definition of a synthesis reaction, where two or more simple substances combine to form a more complex product.

Therefore, the reaction [tex]\( \text{CaO} + \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 \)[/tex] is classified as a:

B. Synthesis reaction.
