Concept: This question tests the understanding of different types of plant tissues and their primary functions, which is fundamental to plant anatomy.

Why (D) is correct:

• A-III: Meristem is responsible for active cell division, leading to growth in plants.
• B-I: Parenchyma is a simple permanent tissue primarily involved in storage of food, water, and waste products.
• C-II: Sclerenchyma provides mechanical support to plants due to its thick, lignified cell walls.
• D-IV: Epidermal tissue forms the outermost protective layer of the plant body, hence its function is protection.

Why other options are wrong:

• (A) Incorrectly matches meristem with storage and parenchyma with active cell division.
• (B) Incorrectly matches meristem with storage and parenchyma with active cell division.
• (C) Incorrectly matches meristem with protection and epidermal tissue with storage.

NEET Tip: Remember the primary function of each tissue type: Meristem (division), Parenchyma (storage/photosynthesis), Collenchyma (flexible support), Sclerenchyma (rigid support), Epidermis (protection).

Correct Answer: (D)
