Since the current range is 7-1 = 6 already, addition of an element x of unknown value cannot decrease this range. Thus, either our range will remain equal to 6 (in case x lies between 1 and 7) or it will increase (in case x is less than 1 or greater than 7) but it can never go less than 6.
Hence, option A, 5 is our answer.
