Answe with explanationin your own words and copy paste or make rando guess else I will report

If a table showing the predicted vs actual values (ordered the same in each dimension) is generated using test data alongside the functions of 'neuralnet' package and only contains non-zero values on the major diagonal, which of the following can be said?"

a) The neural network is hopeless; it cannot predict values very accurately.

b) The neural network can predict accurately in some cases but not all cases.

c) The neural network can predict outputs accurately for all values of input data / predictors.

d) The neural network can predict the outputs of data in the test set perfectly.
