The correct answer is E. All of the above.

The prompt argument in VBA can be made of multiple values concatenated into one string. For example, the following code will display a prompt that says "Enter your name and age:":

prompt = "Enter your name and age:" & vbCrLf & "Name: " & _ vbTab & "Age: "

The prompt argument can also include the vbCrLf constant, which represents a carriage return and line feed. This will cause the prompt to be displayed on two separate lines.

Finally, the prompt argument can include the ampersand symbol to concatenate strings. For example, the following code will display a prompt that says "Your name is: [name]":

prompt = "Your name is: "& name

Therefore, all of the options A, B, and C are true about the prompt argument.

Here is a breakdown of the options:

• Option A: The prompt argument can be made of multiple values concatenated into one string. This is true because the prompt argument is a string, and you can concatenate strings together using the ampersand symbol.
• Option B: The prompt argument can include the vbCrLf constant. This is true because the vbCrLf constant represents a carriage return and line feed, and you can include any character or string in the prompt argument.
• Option C: The prompt argument can include the ampersand symbol to concatenate strings. This is true because the ampersand symbol is used to concatenate strings together, and you can use it in the prompt argument.

Therefore, the correct answer is E. All of the above.
