A Correct answer
Explanation

The many-worlds interpretation of quantum mechanics is an interpretation of quantum mechanics that states that there are many different universes, each with its own unique history. This means that it is possible to travel back in time and change the past, but only in a way that creates a new universe. The original universe will remain unchanged.
