Given that the numbers are listed from greater to smaller.
We have to find n that is smaller than 0 and greater than -1/5 or -0.2. (As in negative numbers "-" sign changes the rule that 0 is greater than -0.5).
Option A is -1/2 that give -0.5 that does not lies between 0 and -1/5
Similarly, Option B gives -0.333 that is too smaller than -1/5.
Option C too not lies between 0 and -0.2 as it comes to be -0.25
Option D gives -0.1333 that obviously is greater than -0.2 and smaller than 0 so it will be the required answer.
