10. [Imitation Learning] Which of the following statements is true regarding the differences between DAgger and simpler forms of imitation learning?

		a) DAgger requires access to an expert policy during both training and test time, whereas simpler forms of imitation learning only require access to the expert during training.
		b) DAgger is only applicable to discrete action spaces, whereas simpler forms of imitation learning can be used with both discrete and continuous action spaces.
		c) DAgger is a form of supervised learning, whereas simpler forms of imitation learning are unsupervised techniques.
		d) DAgger involves iteratively querying an expert policy, whereas simpler forms of imitation learning only use the expert's demonstrations to learn the task.
