Assertion (A): No matter what exception occurs, you can always make sure that some common action takes place for all types of exceptions.

Reasoning (R): The finally block contains the code that must execute.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

What all can be the possible outputs of the following code?

def myfunc (x=None) :
    result = "" 
    if x is None:
       result = "No argument given"
    elif x == 0: 
       result = "Zero"
    elif 0 < x <= 3:
       result = "x is between 0 and 3"
    else:
       result = "x is more than 3"
    return result 
c = myfunc (3.5) 
    print (c)
