Assertion. Modifying a string creates another string internally but modifying a list does not create a new list.

Reason. Strings store characters while lists can store any type of data.

(b)

Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

Explanation
In Python, strings are immutable, meaning once they are created, their contents cannot be changed. Whenever we modify a string, python creates a new string object to hold the modified contents, leaving the original string unchanged. On the other hand, lists in python are mutable, meaning we can modify their contents after they have been created. When we modify a list, python does not create a new list object. Instead, it modifies the existing list object in place. Strings are sequences of characters, and each character in a string can be accessed by its index. Lists, on the other hand, can store any type of data, including integers, floats, strings.
