Given the following result, what is a good conclusion?

a$.$ Since the neural Network has only slightly lower sensitivity and slightly lower AUC than the boosted NN$,$ the simpler

neural network might be preferable.

b$.$ Since the neural Network has slightly lower sensitivity and lower AUC than the boosted NN$,$ the boosted neural network

is definitively the better choice.

c$.$ One must always use the model with higher AUC.

d$.$ None are good conclusions.
