Which statement is used in EML to read data from a business object?

In the context of EML (Entity Manipulation Language), the correct statement to read data from a business object is "READ ENTITIES." This command is specifically designed to retrieve data associated with specified business objects from the underlying data store. When you use this statement, you can specify filters, selections, and other parameters to obtain exactly the data you need.

The focus of this command is on data retrieval, making it essential for querying and accessing information about business objects. This aligns with common programming practices where "read" operations are clearly designated to pull data without altering it.

The other choices involve different data manipulation operations. For instance, updating, modifying, or deleting entities are actions that change the state of the data rather than retrieving it. Therefore, they do not apply in the context of reading or querying data, making "READ ENTITIES" the most appropriate and only correct choice for this question.
