Answer:
The correct option is (a).
Step-by-step explanation:
See the diagram attached.

Therefore, if a rectangle FGHJ is translated by 6 units right and one unit up to produce a rectangle F'G'H'J', then the length F'G' = FG = 3 units and G'H' = GH = 5 units.
So, the correct option is (a). (Answer)
