Complete the FUNCTION statement to create a function named TitleName that takes two character arguments:

The choice that correctly defines the function named TitleName by taking two character arguments is the one that uses the dollar sign ($) notation. In SAS, the dollar sign is used to indicate that the arguments are character types. Therefore, using Name$ and Gender$ specifies clearly that both parameters are expected to be character strings.

Using the dollar sign notation directly with the variable names indicates the data types expected for the function arguments, which is a common convention in SAS programming when defining character variables. This allows for proper handling of string data within the function.

The other options do not correctly represent the syntax for character variables in SAS function definitions. They either include unnecessary quotes or do not use the correct format for declaring character types, which could lead to confusion or errors in understanding the function's parameters.
