What is the syntax used to name a library in SAS?

The syntax for naming a library in SAS is done using the LIBNAME statement. This statement allows you to assign a libref (library reference) to a physical location on disk where SAS can read and write datasets. In the correct syntax, "LIBNAME" is followed by the libref, which is a user-defined name up to eight characters long, and the physical location enclosed in either single or double quotes.

In this case, option C is accurate because it correctly specifies the LIBNAME keyword, the libref without quotes, and the physical location in quotes. This structure is essential for SAS to understand both the reference name and the associated directory path effectively.

The other options do not conform to SAS syntax rules, which is why they are not correct. For example, using "LIBRARY" instead of "LIBNAME" is incorrect because SAS specifically recognizes the "LIBNAME" command for this purpose. Additionally, option D fails to include the keyword entirely, leading to confusion regarding the operation being performed.
