Calcium hydroxide, \(\text{Ca(OH)}_2\), is a compound that dissociates in water to form calcium ions (\(\text{Ca}^{2+}\)) and hydroxide ions (\(\text{OH}^-\)). The hydroxide ions (\(\text{OH}^-\)) make the solution basic.
### Explanation:
- **Acidic** substances release hydrogen ions (\(\text{H}^+\)) in water, which is not the case for calcium hydroxide.
- **Basic** substances release hydroxide ions (\(\text{OH}^-\)) in water. Calcium hydroxide releases two \(\text{OH}^-\) ions per molecule, making it basic.
- **Amphoteric** substances can act as both acids and bases. Calcium hydroxide does not act as an acid.
- **Neutral** substances neither release \(\text{H}^+\) nor \(\text{OH}^-\), which doesn't apply to calcium hydroxide since it releases \(\text{OH}^-\).
Thus, the correct answer is:
**B) Basic**
