Explanation / Answer

***************************************
       Answers:
Q1.
   which built-in-functions has optional arguments...

ANS:
       c.print()
           Because, print is used to print anything what is passed ,
           if we don't pass anything as an argument, nothing will be there,
           but still print function() will executed and nothing will be print.
           Rest built in function must have the respective parameter
          
Q2. One of the following reference can be rebound to another object in memory.

ANS:
       None,
       because all the value are the value type. This means, all are just value
       and hence can't mapped with other particular memory obj. Hence None will go for it.
      
Q3. Determing what parts .. are arguments.

ANS:
       '>,<'
       because here (>,<) is bound with inside ' '
       and this '>,<' is passed inside () as an argument
       where input is inbuilt-function.

Q4.   What object is z is bound ...
ANS:
           None,
           because print(pow(x,y),x) is used to print the value,
           but this has no return type for printing result by print
           function
           Hence None will bound for z value

Q5. which of the following are argument
ANS:
               True options are:
               'four'  
               'enter your age'
               input('enter your age')
                  
                   Explaination:
               'four' is passed as an value for len() function
               'enter your age' is value for len() function
               'input('enter your age') is value for len() function
               where input() is another function
              
Q6. How many agrument this function call has
ANS:
       Here print('1'+'2'+'1,2','1,2','1','+','2')
       if we make comma separated we can easily count argument of function
       Assuming, we have the result as
       '1'+'2'+('1,2'),   ('1,2'),     '1', '+',    '2'
       Now we can easily count there is just 4 comma(,) i.e. 5 argument(ignoring comma inside '()')
       Hence there are 5 arguments inside print() function
