• B. purple anthocyanin pigmentation
• C. older leaves exhibit deficiency symptoms first
• D. all of the above

Answer 1

The correct option is D all of the above

Phosphorus deficiency is a plant disorder associated with an insufficient supply of phosphorus. Darker green leaves and purplish or red pigment can indicate a deficiency in phosphorus. It is most common in lower leaves that are older. This condition is associated with the accumulation of sugars in P-deficient plants. Stems are thinner and leave acquire a leathery texture and tend to curl upwards, sometimes shedding prematurely.

So the correct answer is "all of the above".
