Which of the following statements is false?

• A) A model's summary method shows you the model's layers.
• B) The parameters are the weights that the network learns during training. Our relatively small convnet, needs to learn nearly 500,000 parameters.
• C) In the Output Shape column, None simply means that the model does not know in advance how many training samples you're going to provide-this is known only when you start the training.
• D) By default, Keras trains only the parameters that most affect prediction accuracy.
