The given options about the depth of the tree are:

The correct option to this question is (B) i.e. the depth of this tree is 1.

Because we know that the depth of a node M in the tree is the length of the path from the root of the tree to M. So, in this case,  the depth of node A to node B, C, and D  is 1. So, the correct option to this question is B. i.e the depth of the given tree is 1.
