  • In the first line, we create a tuple t with five elements: 10, 20, 30, 40 and 50.
  • In the second line, we assign t to a new tuple that is a slice of the original tuple from index 1 to index 3 (exclusive). This means we take the elements at index 1, 2 and 3 from the original tuple and make a new tuple with them. The new tuple is (20, 30, 40).
  • In the third line, we use the repetition operator (*) to create a new tuple that is the concatenation of two copies of the previous tuple. This means we join the tuple (20, 30, 40) with itself and make a new tuple with six elements: (20, 30, 40, 20, 30, 40).
  • In the fourth line, we print the value of t , which is the new tuple we created in the previous line.

 

Let’s look at the options and see why they are correct or incorrect:

  • Option a is correct because it matches the value of t that we printed in the last line.
  • Option b is incorrect because it shows the original tuple repeated twice, not the sliced tuple.
  • Option c is incorrect because it shows only the sliced tuple, not the repeated tuple.
  • Option d is incorrect because it shows only two elements from the sliced tuple, not all three.

So, the correct answer is a. (20, 30, 40, 20, 30, 40)
