Select the incorrect statement

Options

A. Museums often have collections of skeletons
B. Separate taxonomic keys are required for each taxonomic category
C. Taxonomic keys are based on the contrasting characters
D. Monograph is useful in providing information for identifications of names of species found in an area

Answer

To solve the question "Select the incorrect statement," we will analyze each of the provided statements one by one to determine which one is incorrect.

### Step-by-Step Solution:

1. **Statement A: "Museum have collection of skeleton."**
- Museums indeed have collections of skeletons, but they also house various other biological specimens, artifacts, and educational materials. Therefore, this statement is generally correct.

2. **Statement B: "Separate taxonomic keys are required for each taxonomic category."**
- Taxonomic keys are tools used to identify organisms based on their characteristics. Different taxonomic categories (like species, genus, family, etc.) may require separate keys for accurate identification. Hence, this statement is also correct.

3. **Statement C: "Taxonomic keys are based on the contrasting characters."**
- Taxonomic keys utilize contrasting characters (features that distinguish one organism from another) to help identify species. This is a fundamental principle of taxonomic keys, making this statement correct as well.

4. **Statement D: "Monograph is useful in providing information for identification of name of the species found in an area."**
- A monograph provides detailed information about a particular taxon, including its classification, characteristics, and sometimes its distribution. However, it does not primarily serve as a tool for identifying species names in a specific area. Instead, it focuses on a specific taxon, making this statement incorrect.

### Conclusion:
The incorrect statement is **Option D**: "Monograph is useful in providing information for identification of name of the species found in an area."
