**Incorrect Statements:**

1. **In network model, data is represented by a collection of records, and relationship among data are represented by links.**
This statement is correct. In the network model, data is represented by records, and the relationships among the data are represented by links. The records contain fields or attributes, and the links define connections between the records.

2. **In hierarchical model, data and relationships among data are represented by records and links respectively.**
This statement is incorrect. In the hierarchical model, data is represented by records, but the relationships among the data are represented by a hierarchical structure. The records are organized in a parent-child relationship, where each child record can have only one parent record.

3. **In hierarchical model, the records are organized as a collection of arbitrary graphs.**
This statement is incorrect. In the hierarchical model, the records are organized in a tree-like structure, where each record has a single parent and multiple children. It is not organized as a collection of arbitrary graphs.

4. **In network model, the records are organized as a collection of trees.**
This statement is incorrect. In the network model, the records are organized as a collection of arbitrary graphs. Unlike the hierarchical model, the records in the network model can have multiple parents and multiple children, allowing for more complex relationships.

Therefore, the incorrect statements are:
- In hierarchical model, data and relationships among data are represented by records and links respectively.
- In hierarchical model, the records are organized as a collection of arbitrary graphs.
- In network model, the records are organized as a collection of trees.

Hence, the correct answer is option D, i.e., all statements are incorrect.
