Answer:
Elena got the dilation portion correct but she reflected incorrectly.
Step-by-step explanation:
We can see she got the dilation correct by multiplying our points by a factor of 2 and moving accordingly from the starting point of D.
What is shown is actually a reflection over a line that we can imagine as running straight up and down from point D. Basically if D was on the y axis we could easily see and say it's reflected over the y axis.
