The correct answer is D. Level 0.
A planning graph is a data structure used in artificial intelligence to represent the state of a problem and the possible actions that can be taken to solve it. The starting level of a planning graph is the level that contains the initial state of the problem. The next level contains the states that can be reached by taking the first action, and so on.
Option A is incorrect because level 3 is not the starting level of a planning graph. Option B is incorrect because level 2 is not the starting level of a planning graph. Option C is incorrect because level 1 is not the starting level of a planning graph.
