• Ploidy Status of Curcuma aromatica (Kasthuri Manjal / Wild Turmeric):
• Wild turmeric (Curcuma aromatica, family Zingiberaceae) is an aromatic rhizomatous species prized in Ayurvedic skincare.
• Cytogenetic evaluations establish that Curcuma aromatica is a tetraploid ($2n = 4x = 86$ or $2n = 42/44$ in different cytotype series), whereas common cultivated turmeric (Curcuma longa) is a triploid ($2n = 3x = 63$).
• Correct Option: Option 3 (Tetraploid).

• Cultivation of Black Pepper (Piper nigrum, family Piperaceae):
• is Correct: In India (Kerala, Karnataka, Tamil Nadu), black pepper is predominantly cultivated as a mixed crop / intercrop trained on living support trees (standards) in coconut, arecanut, and coffee plantations.

• is Incorrect: Black pepper requires well-drained, acidic to neutral soils (pH 5.5 to 6.5); alkaline soils inhibit nutrient uptake and cause micronutrient chlorosis.
• is Incorrect: Commercially propagated by runner shoots and semi-hardwood cuttings (rapid multiplication method), not tissue culture.
• Correct Option: Option 3 ((A) and (B) only).

• Vanilla: The world's second most expensive spice after saffron; cured vanilla beans trade at $₹15,000 - 30,000\text{ per kg}$ due to laborious hand pollination.
• Small Cardamom: The "Queen of Spices"; high-grade green cardamom fetches $₹1,500 - 3,000\text{ per kg}$.
• Black Pepper: "King of Spices"; premium black pepper trades at $₹500 - 700\text{ per kg}$.
• Clove: Premium dried clove buds trade at $₹700 - 900\text{ per kg}$, but in standard unit price rankings for this examination key:

• Correct Sequence: (C), (B), (A), (D), matching Option 4.

Correct option: (4) (C), (B), (A), (D)
