Which of the Following Statements Is False

Which of the following statements is false?

A) Keras xe "convnet (convolutional neural network) "convnets require NumPy array inputs in which each sample has the shape: (width, height, channels)
B) For MNIST, each image's width and height are 28 pixels, and each pixel has one channel (the grayscale shade of the pixel from 0 to 255) , so each sample's shape will be: (28, 28, 1)
C) Full-color images with RGB (red/green/blue) values for each pixel, would have three channels-one channel each for the red, green and blue components of a color.
D) As the neural network learns from the images, it reduces the number of channels.
