(Python) Which of the following is a possible scenario that would prompt you to use a set instead of a list? ( ) When you are working with data of mutable and immutable types. ( ) When you are working with data where understanding frequency is important. ( ) When you are working with data where understanding membership (e.g. uniqueness) is important. ( ) When you are working just with immutable types. OBS: If it is possible to explain the reason for the choice I would be grateful
