Solution
The correct option is B Intercalary
Needle of Pinus possess meristem at intercalary position. In conifers meristems were found in the axils from near the shoot apex. In the more proximal positions the meristems become tangentially elongated to compensate for increases in stem diameter. In some axils the meristems slowly develop into bud primordia, although these buds usually developed few leaf primordia and their apical domes were wide and flat. Associated vascular development was generally restricted to provascular parts.
