Best answer
Correct option is (a) Reverses and stores in the same array

Easiest explanation: The array.join() method is an inbuilt function in JavaScript which is used to join the elements of an array into a string. The reverse() followed by a join() will reverse the respective array and will store the reversed array in the memory.
