Which statement correctly describes the syntax for a named function's header and body?

• A. The keyword function followed by the function name, then the body enclosed in curly braces
• B. The function name followed by parentheses
• C. The keyword var
• D. The class declaration

Answer: (A)

Named function declarations in JavaScript start with the function keyword, followed by the function name, then a list of parameters in parentheses, and the body inside curly braces. The statement described aligns with this structure because it mentions the function keyword, the function name, and the body enclosed in curly braces, which is the essential form of a named function header and its body. The parentheses for parameters are part of the header as well, even if not shown in full here. This is distinct from just writing the function name with parentheses (which would be a reference or a call), from using a variable declaration with the keyword var, or from declaring a class.
