Answer 1

Answer: A

Reason:  Computed properties of swift performs necessary computation each time it is accessed and returns a value rather than storing it. Hence their value can change each time it is called. They are always variables which are build with getter and setter methods using get and set keywords. Default value of the variable should not be assigned. It can be defined by providing the variable name and declare irs type explicity.
