A sub-layer in a neural network processes an input tensor. The sub-layer uses a specific architectural pattern where a residual connection and a normalization step are applied after the main sub-layer function. Arrange the following operations in the correct sequence to compute the final output of this sub-layer.

A sub-layer within a neural network processes an input x. The design specifies that the output of the sub-layer's main function, F(x), is first added to the original input x. A normalization function, Norm(·), is then applied to the result of this addition. Which of the following expressions accurately models this computation?
