A and B are persons standing in corner square as shown in the figure. They start to move on same time with equal speed, of A can move in East or South diretion and B can move in North or West diretion. If in each step they reach in next square and their choice of direction are equlity. If it is given that A and B meet in shaded region, then the probability that they have met in the top most shaded square, is

A

`(1)/(6)`

B

`(.^5C_2)/(.^10C_3)`

C

`(1)/(.^10C_5)`

D

`(1)/(2^5times6)`
