In a structured programming fragment, the line "X = 3" represents an assignment. An assignment occurs when a value is assigned to a variable. In this case, the variable "X" is being assigned the integer value of 3.

This process involves two components: the variable on the left side, which in this case is "X," and the expression on the right side, which evaluates to 3. The assignment operation assigns the right-hand value to the left-hand variable, effectively storing that value for potential use later in the program.

While a command can describe any instruction given to the computer (such as executing an operation), this specific instruction is defined as an assignment due to its nature of assigning a value to a variable. Similarly, a declaration would typically involve introducing a variable into the program, possibly specifying its type, and is not limited to merely assigning a value. A function refers to a block of code designed to perform a specific task when called and does not apply in this context. Thus, identifying this line as an assignment accurately captures its role in structured programming.
