Distance is scalar quantity. Distance will always increase with time . Distance can not be negative .
 
Distance can not decrease with time .
 
( Displacement which is vector can decrease with time or can be negative )
 
In graph-a and graph-d , distance decreases with time .
 
In graph-c , distance becomes negative for some part of time. 
 
Only in graph-b, distance increases with time . Hence only graph-b is correct.
