Before the the data modelling steps there is a data preprocessing step.

In data mining data preprocessing involve the following steps or techniques.

1. Data cleaning.

2. Data integration.

3. Data transformation.

4. Data reduction.

5. Discretization.

Hence before data modelling in the data preprocessing steps Data cleaning, Data reduction, Data transformation are done.

Therefore,

The option All of the above is correct.
