Apical dominance of terminal bud is due to the secretion of auxin (AA) by it. According to Thimann and Skoog (1933) removal of apical buds causes sprouting of lateral buds with stimulation of intercalary meristem and this is the reason that mowing grass lawn facilitates better maintenance. Hence, the correct answer is option 4.
