What is the syntax to create a new dataset named 'temp' in SAS?

The correct way to create a new dataset in SAS is to use the DATA statement, which is why 'DATA temp;' is the right syntax. In this statement, 'DATA' tells SAS that you are starting a new data step, and 'temp' is the name of the dataset you wish to create. This initiates the process of defining the structure and contents of the dataset, allowing for data manipulation or input of observations that follow in the step.

The other options presented do not represent valid SAS syntax for dataset creation. 'CREATE temp;' and 'NEW temp;' do not exist as commands in SAS, and therefore will not perform the intended action of dataset creation. Similarly, 'DEFINE temp;' is not a recognized method for creating a dataset in SAS. Recognizing the specific syntax rules and framework of SAS is crucial for successful programming in this environment.
