Which of the following are format options that can be placed after the format name?

The correct choice, which is DEFAULT=, is a valid format option that can be attached to a format name in SAS. This option allows you to specify a default value that will be used when the format is applied, serving as a fallback if a specific value isn't present in the data. This capability is particularly useful in data management to ensure that when values are missing or undefined in a dataset, a sensible default is used, thus maintaining the integrity and usability of the dataset.

Other options, while they sound relevant, do not align with the standard syntax and capabilities provided by SAS for format options. Understanding the use of DEFAULT= is crucial for SAS programming since it enhances the flexibility and robustness of data processing by controlling how missing or unspecified values are handled.
