since there is no such element in the set, so key error is raised.

Q 5 - Find the output of the code?

def f(a, b = 1, c = 2):
   print('a is: ',a, 'b is: ', b, 'c is: ', c)
f(2, c = 2)
f(c = 100, a = 110)

A - a is: 2 b is: 1 c is: 2

a is: 110 b is: 1 c is: 100

B - a is: 2 b is: 2 c is: 2

a is: 110 b is: 2 c is: 100

C - a is: 0 b is: 2 c is: 2

a is: 110 b is: 0 c is: 100
