The correct answer is D. all of the mentioned.
The function par has two parameters, x and y. The function bar has one parameter, x. The function base has no parameters.
The figure shows the call graph of the three functions. The call graph shows the order in which the functions are called. The function par is called first, then the function bar is called, and finally the function base is called.
The parameters of a function are the values that are passed to the function when it is called. The values of the parameters are used by the function to perform its task.
In the figure, the value of the parameter x is passed to the function par. The value of the parameter y is also passed to the function par. The value of the parameter x is passed to the function bar. The function base does not have any parameters, so no values are passed to it.
The function par returns the value x + y. The function bar returns the value x. The function base does not return any value.
The following is the code for the three functions:
“`python
def par(x, y):
return x + y
def bar(x):
return x
def base():
return None
“`
The following is the output of the code:
“`
par(1, 2)
3
bar(1)
1
base()
None
“`
