• A. A-3, B-4, C-2, D-1
• B. A-4, B-3, C-2, D-1
• C. A-2, B-3, C-4, D-1
• D. A-3, B-2, C-4, D-1

Answer 1

Answer:

C. A-2, B-3, C-4, D-1

The correct matches for the deficiency symptoms and their associated minerals are:

• (a) Interveinal chlorosis of leaves, first in younger leaves matches with - Fe (Iron). Iron is an immobile nutrient, so its deficiency symptoms appear first on younger leaves.

• (b) Interveinal chlorotic and necrotic spots on leaves matches with - Mn (Manganese). Manganese deficiency often causes speckled or necrotic spots along with interveinal chlorosis.

• (c) Bronzing of the leaves matches with - Cl (Chlorine). Chlorine deficiency can lead to wilting and a bronzing of leaves.

• (d) Interveinal chlorosis of leaves, first in older leaves matches with - Mg (Magnesium). Magnesium is a mobile nutrient, so its deficiency symptoms, including interveinal chlorosis, first show up in older leaves as the plant moves the available magnesium to new growth.
