At the intersection, * * * has three different choices, BE, BF and BC, where BC is the right direction, so the probability of choosing the right intersection is 1/3.

At a fork in the road, * * * has two choices: CD and CG, where CD is the right direction, so the probability of choosing the right intersection is 1/2.

Liu correctly met the requirements of point D:

1. Choose the right direction at the intersection.

2. Choose the right direction at the fork in the road

Two conditions must be met at the same time to reach point D correctly.

So the probability is1/3 *1/2 =1/6. Choose B.
