Final answer:
The corresponding angle of ∠ J in △ JKL when compared to △ NOP, based on the similarity statement given, is ∠ N.
Step-by-step explanation:
The similarity statement △ JKL≈ △ NOP means that the corresponding angles of the two triangles are equal. 
Therefore, the corresponding angle of ∠ J in △ JKL would be the first angle in △ NOP based on the order given in the similarity statement. In this case, ∠ J corresponds to ∠ N. 
So the answer to the question is ∠ N, making option D the correct choice.
