A bus travels distance `x_(1)` when accelerates from rest at constant rate `a_(2)` for some time and after that travels a distance `x_(2)` when decelerates at a constant rate `a_(2)` to come to rest. A student established a relation `x_(1)+x_(2)=(a_(1)a_(2)t^(2))/(2(a_(1)+a_(2)))`.
Choose the correct option(s).

A

The relation is dimensionally correct

B

The relation is dimensionally incorrect

C

The relation may be dimensionally correct

D

None of the above
