Applying step_dummy() to predictors

You are using the telecom_training data to predict canceled_service using avg_data_gb and contract as predictor variables.

| canceled_service | avg_data_gb  | contract         |
| yes              | 7.78         | month_to_month   |
| yes              | 9.04         | month_to_month   |
| yes              | 5.08         | one_year         |
| no               | 8.05         | two_year         |

In your feature engineering pipeline, you would like to create dummy variables from the contract column and leave avg_data_gb and canceled_service as is.

Which step_*() function from the options will correctly encode your recipe object?
