Answer:
Correct answer is  "sequence of transformations produces  L'M'N' from LMN is translation 5 units down and 2 units to the left followed by a reflection across the y-axis"
Step-by-step explanation:
Step 1:  reflection of ΔLMN will be on left side of the y axis.
Step 2: move two units to the left from the reflection's position.
Step 3: move L'M' 5 units downward from the it's location in the reflection.
By following the above mentioned steps we will get the given transformation L'M'N' from LMN.
