The correct answer is: D. Assignment<\/strong><\/p>\n

An assignment statement is used to assign a value to a variable. It is the most basic type of statement in any programming language. The syntax of an assignment statement is as follows:<\/p>\n

variable = expression;<\/code><\/p>\n

where variable<\/code> is the name of the variable to be assigned a value, and expression<\/code> is the value to be assigned to the variable.<\/p>\n

For example, the following statement assigns the value 10 to the variable x<\/code>:<\/p>\n

x = 10;<\/code><\/p>\n

Assignment statements can also be used to assign multiple values to multiple variables, as follows:<\/p>\n

x = y = z = 10;<\/code><\/p>\n

In this case, the value 10 is assigned to all three variables x<\/code>, y<\/code>, and z<\/code>.<\/p>\n

Assignment statements are essential for storing data in variables and for performing calculations. They are the building blocks of all programs.<\/p>\n

The other options are incorrect because they are not used to assign a value to a variable.<\/p>\n
