To declare the variable in vb . . . . . . . .-this key word is used

The correct answer is C. dim.

To declare a variable in VB, you use the keyword “dim”. For example, the following code declares a variable named “x” of type “integer”:

dim x as integer

The keyword “dim” is followed by the variable name and the type of data that the variable will store. The type of data can be one of the following:

• Integer
• String
• Boolean
• Double
• Single
• Currency
• Date
• Object

Once you have declared a variable, you can use it in your code. For example, the following code assigns the value 10 to the variable “x”:

x = 10

You can then use the variable “x” in your code. For example, the following code prints the value of “x” to the console:

print x

The output of this code would be “10”.

The keywords “bottom”, “top”, and “frame” are not used to declare variables in VB.
