To determine the winner using pairwise majority voting, we compare each pair of options and choose the option with the most votes.

First, we compare A and B. Two voters prefer A, and three voters prefer B. B wins.

Next, we compare B and C. Three voters prefer B, and two voters prefer C. B wins again.

Finally, we compare B and D. Three voters prefer B, and two voters prefer D. B wins for the third time.

Therefore, the policy of following the expert's advice to remove every tree (B) wins under pairwise majority voting. However, it is also worth noting that this method doesn't take into account the intensity of the preferences, and one alternative might win without achieving the best general satisfaction.
