10. Regarding neural networks (NNs) that Alef might potentially implement, which of the following statements is least accurate?

A. NNs must have at least 10 hidden layers to be considered deep learning nets.

B. The activation function in a node operates like a light dimmer switch since it decreases or increases the strength of the total net input.

C. The summation operator receives input values, multiplies each by a weight, sums up the weighted values into the total net input, and passes it to the activation function.
