If we have a dataset of $500028$ X $28$ grayscale images and we represent this using a $3$D tensor

Question $6$ options:

The second axis of this tensor would be the batch axis, indicating the number of samples in the batch for training a deep learning model

The first axis of this tensor would be the batch axis, indicating the number of samples in the batch for training a deep learning model

The data type $($dtype$)$ of this tensor would be equal to the number of samples in the batch for training a deep learning model

The 'shape' attribute of a tensor object, queried in Python using $\text{'}.$shape', would equal the number of samples in the batch for training a deep learning model
