Total time = 6 hours
Speed of the boat in still water = 4 km/hr
Let the distance between M and N be D
and the speed of the stream be x
Speed of the boat in still water = 4 km/hr
Let the distance between M and N be D
and the speed of the stream be x
Since the speed of the stream (x) is not given, the distance D cannot be determined

Given information:
Speed of boat in still water = 4 km/hr
Time taken to travel from M to N downstream and back from N to M upstream = 6 hours
Let the speed of the stream be x km/hr.
Then, speed downstream = (4 + x) km/hr
And, speed upstream = (4 - x) km/hr
Let the distance between M and N be d km.
Formula used:
Distance = Speed x Time
Calculation:
Distance downstream = (4 + x) x t1
Distance upstream = (4 - x) x t2
Total distance = (4 + x) x t1 + (4 - x) x t2 = d (as the boat travels from M to N and then back to M)
Also, we know that t1 + t2 = 6 (as the total time taken is 6 hours)
Solving the above two equations, we get:
d = 12x
Now, we have two variables (d and x) and only one equation. Hence, we cannot find the exact value of the distance between M and N.
Therefore, the correct answer is option D - Data inadequate.
