Solution

The correct option is B Secondary xylem
Annual rings are formed due to unequal activity of vascular cambium. The activity of cambium does not remain same. It is changeable in the whole year. Activity of vascular cambium is affected by physiological and environmental factors. In winter or autumn season the activity of the cambium is less and the secondary xylem or wood formed is not extensive through the vascular cambium.
