• A. A, B, E only
• B. A, B, C only
• C. A, C, D only
• D. A, B, D only

Hint:

Mango Variety Quick Memory: - Chausa = Late season (North India). - Rat = Neelam $\times$ Alphonso (Free from Spongy Tissue). - Amrapali = Dashehari $\times$ Neelam (High Density Planting).

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question requires evaluating statements related to mango (Mangifera indica) cultivars and ecological requirements to select the true statements.

Step 2: Statement Alysis:

• Statement A: True. Chausa is a premier late-maturing sweet cultivar of North India (maturing in July--August).
• Statement B: True. Mango is classified ecologically as a tropical fruit crop, though it adapts well to subtropical frost-free zones.
• Statement C: False. Most commercial mango cultivars in India are landraces/selections (e.g., Alphonso, Dashehari, Langra), not artificial hybrids.
• Statement D: True. 'Rat' (a hybrid cross of Neelam $\times$ Alphonso developed at FRS Vengurle) is completely resistant to the physiological disorder known as spongy tissue.
• Statement E: False. 'Langra' is an important commercial variety of North and East India (Varasi, UP), not South India.

Step 3: Detailed Explation:

• Correct true statements: A, B, and D.
• Incorrect statements: C (most varieties are selections) and E (Langra belongs to North India).
• Therefore, option (D) listing A, B, D only is correct.

Step 4: Fil Answer:
The true statements are A, B, D only. Thus, option (D) is correct.
