The correct answer is Translation of negative 6 units x, 1 unit y composition reflection across the x-axis.
Here's the step-by-step breakdown:
Parallelogram A B C D to A' B' C' D':
Reflection across the x-axis: This flips the parallelogram across the x-axis, resulting in A' B' C' D'.
Parallelogram A' B' C' D' to A" B" C" D":
Translation of negative 6 units x, 1 unit y: This shifts the parallelogram 6 units to the left and 1 unit upwards, resulting in A" B" C" D".
Therefore, the overall composition of transformations is Translation of negative 6 units x, 1 unit y composition reflection across the x-axis.
