Solution

The correct option is C
Order remains the same

If rational numbers are arranged in ascending order and every number is increased/decreased by the same number, then the order of the numbers does not change.
For example, consider the rational numbers arranged in the ascending order, as shown below.
$\frac{2}{5} < \frac{3}{5} < \frac{4}{5}$
Adding 2 to each rational number above, we get,
$\frac{12}{5} (= 2.4) < \frac{13}{5} (= 2.6) < \frac{14}{5} (= 2.8)$
