The least possible Venn diagram for the statements is as below:
Conclusions: I. No pomegranate is a plum → True (It is true as "all pomegranate are tree" and "no tree is a plum" so no pomegranate is a plum) II. No plum is a tree → True (It is true as "no tree is a plum" so plum cannot be a tree) III. Some trees are pomegranate → True (It is true as "all pomegranates are trees" so some trees are definitely pomegranate) Hence, the correct answer is "All the conclusions follow".
