   except ZeroDivisionError: 
      print('Divided By Zero! Not Possible! ') 
   except: 
      print('Its an Exception!') 
def func(): 
   print(1/0) 
main()

A ) ‘Its an Exception!’

B ) ‘Divided By Zero! Not possible!’

C ) ‘print this after function call’ followed by ‘Divided By Zero! Not Possible!’

D ) ‘print this after function call’ followed by ‘Its an Exception!’

Answer : B

Explanation

The function ‘func’ will not run because it contains an exception. So in try and expect block. The function called under try will not run and will move to except block which defines the type of exception present in the function ‘func’. Thus block of statements present in except ZeroDivisionError is printed.
