Final answer:
The false statement is that the keyword null indicates that a method will perform a task but will not return any information. The null keyword is actually used to indicate that a variable is not referencing any object. Other provided statements about method parameters, local variables, and braces delimiting a method's body are true.
Step-by-step explanation:
The statement "Keyword null indicates that a method will perform a task but will not return any information" is false. The keyword null in programming languages such as Java is used to signify that a variable does not currently refer to any object and not to describe a method's behavior. Therefore, the correct statement is, "null is a value that can be assigned to a variable to indicate that it does not currently refer to any object."
The statement "A method's parameters are local variables of the method" is true. Parameters of a method are indeed treated as local variables within the scope of that method.
The statement "Variables declared in the body of a particular method are local variables and can be used only in that method" is also true. Local variables are defined within a method and cannot be accessed outside of that method's scope.
Lastly, the statement that "Every method's body is delimited by left and right braces ({ and })" is true. In languages like Java and C#, methods are indeed delimited by curly braces, which define the beginning and end of a method's body.
