Concept: This question tests your knowledge of different types of plant tissues and their specific functions, particularly focusing on meristematic and permanent tissues.

Why (B) is correct:

• a-(iii) Apical meristem: Located at the tips of roots and shoots, responsible for increase in length (primary growth).
• b-(iv) Lateral meristem: Includes vascular cambium and cork cambium, responsible for increase in girth or diameter (secondary growth).
• c-(i) Intercalary meristem: Found at the base of leaves or internodes, responsible for elongation in grasses and regeneration of lost parts.
• d-(ii) Permanent tissue: Composed of cells that have lost the ability to divide and are specialized to perform specific functions, forming the bulk of the plant body.

Why other options are wrong:

• (A) Incorrectly matches lateral meristem with primary growth and intercalary meristem with secondary growth.
• (C) Incorrectly matches lateral meristem with primary growth.
• (D) Incorrectly matches apical meristem with secondary growth and permanent tissue with primary growth.

Common Mistake: Students often confuse the roles of apical and lateral meristems, associating both with overall plant growth without distinguishing between length and girth.

NEET Tip / Mnemonic: Remember 'A' for Apical and 'L' for Length (primary growth), and 'L' for Lateral and 'W' for Width (secondary growth).

Correct Answer: (B)
