Training Objective of the Standard BERT Model

During a self-supervised pre-training process, a model is given an input sequence where one word has been replaced by a special symbol, for example: 'The quick brown [MASK] jumps over the lazy dog.' The model's objective is to predict the original word, 'fox'. Which of the following is the direct input used by the final output layer to make this specific prediction?

Original Sequence for Masking and Deletion Examples

Arrange the following steps in the correct order to describe the process of pre-training an encoder model using a masked language modeling objective.
