print(my_tuple[1])
a) 1
b) 2
c) 3
d) Error: Tuples are immutable
Answer: b
Explanation: Tuples are ordered collections, and indexing starts from 0. So, my_tuple[1] refers to the element at index 1, which is 2.
Q2. Which of the following operations is not valid for tuples in Python?
a) Concatenation
b) Indexing
c) Appending
d) Slicing
Answer: c
Explanation: Tuples are immutable, so appending elements to a tuple is not valid in Python.
