A function definition expression can be called as __________*1 pointa) Function prototypeb) Function literalc) Function callingd) Function declaration

The correct answer is b) Function literal.

A function literal is a specific way to define a function using an expression that generates the function object, usually implied within the context of some programming languages. The term “function definition expression” directly aligns with this concept, as it refers to the actual creation of a function instance.

To clarify:

• Function prototype refers to the declaration of the function that specifies its name, return type, and parameters but does not provide the body of the function.
• Function calling involves executing a function.
• Function declaration is synonymous with a prototype in many contexts but typically does not include the internals of the function.

Thus, in this case, "function literal" is the most appropriate choice.
