Key Points
- A tree’s trunk grows primarily from the tips (apical meristems) rather than pushing older wood upward. Although the trunk thickens (increases in girth) over time due to lateral growth, any fixed point along its length does not shift significantly up or down.
- Therefore, a nail driven into the trunk at 1 m above the ground will still be at roughly the same height two years later, even though it may become more embedded as the trunk thickens. Hence Correct answer is Option 1.
