Explanation

We are given the image below:

We are required to determine the sequence of transformations shown.

We know that from image 1 to image 2, there is a reduction in size. Therefore, we can say that there is a dilation by a scale factor of 1/3.

From image 2 to image 3, we have:

[tex]\begin{gathered} A(x,y)\to A^{\prime}(x,-y) \\ i.e. \\ (1,1)\to(1,-1) \\ (2,1)\to(2,-1) \\ (2,3)\to(2,-3) \\ Hence,\text{ }there\text{ }is\text{ }a\text{ }reflection\text{ }over\text{ }the\text{ }x\text{ }axis \end{gathered}[/tex]

Hence, option D is correct.
