Q 4 - Suppose we have two sets A & B, then A<B is:

A - True if len(A) is less than len(B).

B - True if A is a proper subset of B.

C - True if the elements in A when compared are less than the elements in B.

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

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

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

   print(x[length-1],end='' '') 
   rev_func(x,length-1) 
x=[11, 12, 13, 14, 15] 
rev_func(x,5)

A - The program runs fine without error.

B - Program displays 15 14 13 12 11.

C - Program displays 11 12 13 14 15.

D - Program displays 15 14 13 12 11 and then raises an index out of range exception.

In the print statement of rev_func we use the index value of list x. We decrement the value of length of function because it becomes the index of x in the print statement.
