Final answer:
Among the options 'print,' 'input,' 'if,' and 'capitalize,' the term 'if' is not a function but a control structure.
The others are functions that perform specific actions in programming languages.
Step-by-step explanation:
The following options present a mix of functions and a control structure: print, input, if, and capitalize.
Among these, "if" is NOT a function; it is a control structure used in programming to execute code based on certain conditions.
The rest are indeed functions within various programming languages.
Print is typically used to display output to the user, input is used to receive input from the user, and capitalize is a method in Python used to convert the first character of a string to uppercase.
