Correct answer
D. The spring wood is dark in colour and has lower density.
Step-by-step solution
In spring season cambium is more active and produces large quantity of xylem having vessels with wider lumen. The wood formed during this season is called spring wood or early wood. In winter, the cambium is less active and forms fewer xylary elements that have narrow vessels, and this wood is called autumn wood or late wood. The spring wood is lighter in colour and has a lower density whereas the autumn wood is darker and has a higher density.
