Approach Solution -2
Comparing deficiency symptoms: Molybdenum deficiency typically shows as whiptail or scorching of leaf margins; iron deficiency causes interveinal chlorosis of young leaves; magnesium deficiency causes interveinal chlorosis of older leaves.
None of these three matches discolouration and breaking or dropping of leaf buds.
Boron, however, is essential for cell wall integrity and meristematic tissue development, and its deficiency specifically causes bud discolouration, brittleness, and death or dropping of terminal and lateral buds, matching the description exactly.
