Answer 1

option number C is the correct answer....

Answer 2

When an argument is passed by value The function copies the value of the argument to its own variable.

An argument is passed by value?

• The copy is the target of the function. This implies that if a function modifies the value of an argument supplied by value, the effect is limited to that function; the copy changes, but the original value in memory remains unchanged.

• When a method receives an argument by value, it receives a copy of the argument but does not have access to the original.

• The parameter of the called functions will be the same as the callers' provided argument when passing by reference.
